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 second track:

TX polarization           RCP
RCV polarization          LCP
Frequencies:              4
Dwell:                    20 seconds

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.

Using Solution 17

We will not split the difference in the txoffsets: target is far enough
away that we're fine with the switching.

0143: Rays says the VAX is working fine today.  configuration files are running
fine.  They didn't do anything in the interim.

0203: ready to go.  waiting for txauth to start.  

I noticed we don't have much disk space, so Randy is deleting files from 
earlier this spring and earlier, except for ML14.

Starting 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:       4096 for 0.244-Hz resolution

CW objective: verify that we have echoes, then go to ranging.

cw loopback OK

023019: beam is up

1st run: forgot to restart accumulation; added onto loopback

2nd run: obvious echoes.  Doppler corr'n -0.5 +/-0.3 Hz.  EPOCH= 1999 Jul 20 02:40:00

Bandwidth is about 2 Hz or 0.5 Hz wider than yesterday.

Stop and go to 10 usec ranging.


Configure for 10 usec ranging
=============================
127 x 64 10-usec single sample

baud            10 usec
code            127
gates           127
FFT             64
CLT             11
ncoh            5
bandwidth       157.48 Hz   
resolution      2.46 Hz 
TXOFF           +25 Hz  ==> Echo should come in at almost exactly +10 Doppler bins
incoh sums       =>  sec/record

Echo should be nearly match-filtered in Doppler.

clt ok
cold sky ok

024833: beam is up

Echo!  Very strong.  But not as far over in Doppler as it should be---only
about 4 cells instead of 10.  Turns out we used the wrong setup, not the one
I requested.  We got 2 sums with 6.15 hz res'n, not 2.46 Hz.

Minor trouble updating the display.

Echo is in gate 79.  Only one range gate.

So 79-11 = 68 gates modulo 127 
or 680 usec modulo 1270

Possibilities:

-4400
-3130
-1860
-590
680
1950
3220
4490
5760



Configure for 11 usec
=====================
127 x 64 11-usec single sample.

baud            11 usec
code            127
gates           127
PRP             1397
FFT             64
CLT             11
ncoh            5
bandwidth       143.16 Hz   
resolution      2.236 Hz
TXOFF           +25

clt OK
cold sky OK

030723: beam is up

Echo!  near gate 106.  Zoom in...
Echo is in gate 107.

So 107-11 = 96 gates modulo 127 
or 96(11usec) modulo 127(11) = 1056 modulo 1397

-4532
-3135  <== BINGO  
-1738
-341
1056
2453
3850

Ambiguity is resolved: -3132.5 usec +/- 10 usec at 1999 Jul 20 03:00 UTC

3 milliseconds or about 1/2 of Jon Giorgini's 1-sigma uncertainty.


Stop and go to 1 us

255 x 256 1-usec single sample.

baud		1 usec
code		255
gates		255
PRP		255 usec
FFT		256
CLT		11 ?
ncoh		153
bandwidth   	25.6 Hz   
resolution	0.100 Hz
TXOFF	        +5 Hz (+50 Doppler bins, but echo is offset by -0.5 
                       Hz, so total offset is about 4.5 Hz.  Expect 
                       echo center near bin 173)

CLT: problem: came in at about bin 17.  it wrapped in Doppler--we weren't using
the setup I requested.  Ray and Carl were worried the toutatis setup 
wouldn't work so they tried modifying a JX setup without telling me.
Then the txoff I chose made it wrap.   

The set up they loaded was: JX1S0100 127 gates 64 point FFT 
with 1 us x 0.1 Hz.

We then loaded the toutatis setup above but there was horrible DC,
so we reverted back to the JX setup.  We chose TXoff = 2.3 Hz.  That put
the echo pretty far over in Doppler.  We skipped the CLT and cold sky
because we were running out of time (do in postcal).  

Time for most of 2 runs.  

033528: beam up

BAD DC!  May still have echo; swamped level of display. (run 1)

2nd run--had to turn of txmitter early due to end of tx window.
will get 16 sec of noise at end.

Echo, but levels were set such that we saw only three scattered
points.  Need to reduce data to see what we have.  DC may complicate
background removal and normalization.  

Ray and Carl are working on the Toutatis setups.  They can do loopbacks 
now to make sure the setups work.

==============
Good track: obtained a range and resolved the target in delay.
Substantial improvement to the orbit.
