<b>During the first track (!)</b>, the strategy is to move from cw to
coarse-baud ranging as soon as possible.  

The echo bandwidth (for D = 0.7 km, guess P = 4 hr) will be about 
(17.5 Hz)(cos LAT), where LAT is the subradar latitude.  The echo delay 
depth should be a few microseconds.

The Doppler uncertainties during the first track are such that we'll use 
a relatively wide bandwidth and short FFT for the initial detection.


During the first track (!), the strategy is to move from CW to 
coarse-baud ranging to high-resolution imaging as soon as possible.

The echo bandwidth (for D = 3 km, P = 12 days) will be about
(1.0 Hz)(cos LAT), where LAT is the subradar latitude.  The
echo delay depth should be within a factor of two of 10 microseconds.

Starting CW setup for the first track:

TX polarization           RCP
RCV polarization          LCP
Frequencies:              4
Dwell:                    20 seconds
Bandwidth:                4000 Hz
Sampling interval:        2500 x 0.1 usec
VMT FFT for PSD files:    4096 for 0.977-Hz resolution, but we'll shrink
                          this if the echo is narrow.

Ray Jurgens and Carl Franck have added 3 new configurations that
provide range over-sampling.  The original long baud configurations
are set up as follows:

Config.    baud   over  range   FFT     coh     BW      Res
           micro  samp  gates   freqs   sums    Hz      Hz
           sec

JX1XS0700   7.0     1   127     64      3       375     5.86
JX1XS1000  10.0     1   127     64      2       394     6.15
JX1XS1100  11.0     1   127     64      2       358     5.59

We added the following to the JX set:

JX1XS0350   7.0     2   254     64      3       375     5.86
JX1XS0500  10.0     2   254     64      2       394     6.15
JX1XS0550  11.0     2   254     64      2       358     5.59

These new configurations have exactly the same coverage in range
and Doppler frequency as the previus set.  They provide 2 range samples
per baud filling in the deep hole between gates in the original set.  The
only disadvantages in using these are that they record more data in a 
given amount of time for the same amount of integration, and the display
is crowded if you try to show all gates at one time.  

SNR tests using the these are essentially identical to the originals.

BEGIN ELECTRONIC LOG

Present: Benner, Rose, Jurgens, Frye, Franck, Choate, Shepard, Ostro, Jao

Jon Giorgini updated to soln 17 yesterday but the differences were so small
that I decided to stay with soln 15.

1849: Still have more than an hour before tx window opens.  Observing Mercury with
the long-code setup.  Having problems printing again, possibly because there was a
power outage.  The computers and printer went down and rebooted but now we can't print.
I sent Richard Zinar e-mail asking for help.

2032: There's a discrepancy between where we're pointed and where we should be 
pointed.  Randy went over to try to figure it out.

2045: The discrepancy seems to be an EAC display problem.  We're going to start.
We aren't going to split the offsets --it takes 4-5 seconds to issue the command to
the EAC and to get it back.  For a 100 s RTT that's no problem, but it won't be 
tolerable for NW2 later in the track.




TX Power = 430 kW for CW

 RCV polarization             1=RCP=OC=xxx K at zenith

Ch 1 Tsys = 15.96 on point (el=48.69)
Ch 2      = 17.78

Starting CW setup for first track:

 Sampling interval:           2500 x 0.1 usec
 VME FFT for PSD files:       4096 for 0.977-Hz resolution

Tsys may not be good due to ACSM problem.

211251: beam is up

We have echoes!  Very strong.  

Echo is unresolved.

Doppler corr'n ~ 2 Hz.

Switch to 1000 Hz BW, 8 K FFT for res'n = 0.122 Hz



Will verify echoes and then switch to 1 us imaging.

Change: Switch to 16 K fft, keep 40kHz BW. Same res'n= 0.122 Hz

Resolved the echo.  bandwidth is about 1.4 Hz.  Center freq
is offset by about +1.5+/-0.4 Hz.

Joseph arrived around 2120

Ray and Carl are configuring for 1 us x 0.1 Hz (code=255, TU1XS08).

Choose TXoff=+4 Hz

TXOFF	        +4 Hz (+40 Doppler bins, but echo is offset by +1.5 
                       Hz, so total offset is about 5.5 Hz.  Expect 
                       echo center near bin 183)

2306: Carl and Ray are still trouble shooting the VAX.  They restarted it.  They 
think they've isolated the problem.  We've lost a lot of time.

0012: Ray and Carl are still working on the problem.  We'll go 
until 0100 and then I'm going to do more CW before we switch targets.

Update the orbit

This is clearly wrong.  I think my problem arose when I goofed up copying 
the astrometry from emacs into osod.  

We're about to resume CW so I sent Jon Giorgini an e-mail asking for help.




Go back to CW using the following setup:

TX  polarization              RCP
 RCV polarization             both
 Frequencies:                 2
 Dwell:                       30 seconds
 Bandwidth:                   500 Hz
 Sampling interval:           20000 x 0.1 usec
 VME FFT for PSD files:       8192 for 0.061-Hz resolution

Ptx = 420 kW

We're running with 30 sec dwells because longer dwells haven't been working.
With 30 sec dwells we'll be sure to get a complete look/dwell.  If we ran
the same BW & FFT with 4 hops we'd be close enough that the boundary between
hops could have prevented us from getting a complete cycle/dwell.  The echoes
are strong enough that the reduction in SNR isn't a problem.

Use macro B.

Ray says we can't use the long-code approach because the finest res baud
is 40 usec.  An alternative is to retrieve the block V from JPL and try 
that.  We won't be able to get ranges because there's an ambiguity of about
one baud but we might get images as fine as 0.25 us.

0124: Almost ready to resume CW.  

0134: EAC is having trouble loading macro B; otherwise we're ready

013903: beam is up

levels were screwed up; first 1-2 runs bad.

0145: we have echoes.

We're going to do a 11 runs total (10 good) and then switch to NW2.
That will give us 20 looks so self noise will be about 22%.  Problem
is that we don't want to eat into too much of our time for NW2.

Echo bandwidth is about 1.4 Hz.  Hint of a central dip, but that could
also be self noise.

021542: switch targets to 1999NW2


0617: Return to 1999 JM8 imaging after failing to range 1999 NW2.
Carl figured out the ranging problem.  

Configure for 1 us x 0.1 Hz (TU1XS08)
=====================================
255 x 256 1-usec single sample.

baud		1 usec
code		255
gates		255
PRP		255 usec
FFT		256
CLT		13-14
ncoh		153
bandwidth   	25.6 Hz   
resolution	0.100 Hz
TXOFF	        +4 Hz (+40 Doppler bins, but echo is offset by +1.5 
                       Hz, so total offset is about 5.5 Hz.  Expect 
                       echo center near bin 183)

Macro B

0641: loopback and cold sky OK.

064059: beam is up

0645: where's the echo?  should have seen it by now.

0650: end of 3 runs; no echo.  Stop and return to CW

CW setup

TX  polarization              RCP
 RCV polarization             both
 Frequencies:                 4
 Dwell:                       20 seconds
 Bandwidth:                   1000 Hz
 Sampling interval:           10000 x 0.1 usec
 VME FFT for PSD files:       8192 for 0.122-Hz resolution

It's a race to get this going.  We have 17 minutes left.

cw loopback OK

070424--beam is up

Obvious echo on first run
bandwidth ~ 1.5 Hz, Doppler corr'n = +1.6-1.7 Hz (center)
These results are consistent with what we got before

So...there are no crushing problems with pointing, the macro,
the PO...  Ray suggested we might have overspread it in both
dimensions.  Barring some flash of insight tonight by Ray and/or
Carl, we'll start tomorrow's track with 11 and 10 usec x 1 Hz to
match filter the echo in both dimensions.

PROBLEMS
========
0. There was a power outage between Friday night and this morning.  All the computers
   went down.  Messed up the connection to the printer falcon (the HP).  Had to resort
   to the low level printing command: /opt/hpnp/bin/hpnpf [-n] -x 158.154.2.23 filename.
1. VAX would not load setups.  Not even the tests.  Lost a lot of time.
2. Discrepancy in the acsm az & el values and the EAC display.  Apparently
   just a display problem--we got echoes immediately so the pointing is fine.
3. NO IMAGES OF EITHER TARGET.  What's wrong with the ranging system?


Things to do before leaving
===========================
1. transfer ranging data -> intruder then ftp to JPL 	==> Done
2. transfer cw data      -> intruder then ftp to JPL	==> Done
3. transfer tx/rcv logs to intruder and then to JPL	==> Done
4. write protect all data and log files	at JPL		==> Done
5. update website on reason				==> 
6. set up log file for tomorrow				==> 
7. critique 						==> Done
8. get the data package					==> Done
9. back up the data ->  exabyte tape & write protect it	==> Done
10.organize hardcopies  				==> Done
11.ftp observational log -> JPL and write protect it	==> Done
12.e-mail brief summary of results -> co-authors        ==> Done
13.e-mail brief summary -> Ralph & Larry                ==> Done

Draft critique
==============
Major milestone: first radar detection of 2 new NEAs in only 6
hours, which is a record.  Strong echoes from both targets.  
Good support by all personnel in a very demanding track.  
Primary object, imaging, has not yet been achieved.
