## TARS

- “The primary mission of TARS is to provide critical low- altitude radar surveillance of the southern approaches into the US and selected areas of the Caribbean. This program supports air sovereignty and counter-drug operations conducted by DoD (North American Aerospace Defense Command and US Atlantic Command) and Law Enforcement Agencies (US Customs Service and US Coast Guard).” [http://www2.acc.af.mil/lg/cons/lgco/tars.htm]

## ETL History with TARS Part I

- 404 MHz Profiler El/Az Yagi Antenna
- 1988: Strauch, Moran, Bedard, Nishiyama, Merritt
- Real-time winds and Acceleration of RASS development
- 915 MHz
- 1990 or 1991: Jordan
- Procurement Package developed
- Developed in mid 1990’s, then cancelled...

- Presentation: A New ETL 449 MHz Wind Profiler for TARS

- Feb. 4, 2002

**Notes:**
ETL has worked with the TARS program going back to at least 1988. A 404 MHz wind profiler was installed at Ft. Huachuca, AZ for almost a year providing real-time winds. A 915 MHz system was also tested. Later, in the mid 1990’s,  ETL developed a procurement package to purchase several wind profilers. This procurement effort was later cancelled. 

## 404 MHz Radar, 1989

- Presentation: A New ETL 449 MHz Wind Profiler for TARS

- Feb. 4, 2002

**Notes:**
ETL 404 MHz Radar Wind Profiler set up several miles from the TARS site. The antenna was composed of multiple Yagi antennas, positioned on a elevation-over-azimuth mount. The mount would reposition the antenna once every minute to collect horizontal wind profiles. 

## 404 MHz Tests as TARS Site

- Presentation: A New ETL 449 MHz Wind Profiler for TARS

- Feb. 4, 2002

**Notes:**
404 MHz radar tests were also conducted at the TARS site.

## ETL History with TARS Part II

- ETL Aerostat Weather Workshop
- 1998, Bedard
- ETL 449 MHz Tests at Ft Huachuca
- “Aerostat Meteorological Hazards Handbook”
- Feb. 2001, Bedard
- MOU with ETL for 449 MHz wind profiler
- 1999, Post
- ET4 449 MHz Tests at Ft Huachuca
- Oct. 1999
- Operational 449 MHz Radar Wind Installed
- Oct. 2001

- Presentation: A New ETL 449 MHz Wind Profiler for TARS

- Feb. 4, 2002

**Notes:**
Al Bedard (of ETL) organized a workshop at ETL to bring flight directors and others concerned with aerostat flight safety together. With this new kick-off for improved weather support technology, a handbook was produced, and eventually a 449 MHz profiler was permanently installed at Ft. Huachuca for real-time winds support.

## Portable 449 MHz Tests

**Oct 1999**

- Presentation: A New ETL 449 MHz Wind Profiler for TARS

- Feb. 4, 2002

**Notes:**
In 2000, a portable ETL 449 MHz system was also temporarily setup at the TARS site to test for interference and to see if winds could be acquired if the radar was located directly at the TARS site. 

## Partnership Benefits

- _Air Force_ does not have to become Radar Wind Profiler Experts
- _NOAA/NWS_ obtain quality data in data-sparse regions
- _NOAA/ETL_ are able to stay abreast of and implement latest techniques for RWP’s

- Presentation: A New ETL 449 MHz Wind Profiler for TARS

- Feb. 4, 2002

**Notes:**
Benefits to tax payer and to involved government agencies. 

## Direct NOAA Impacts

- Improve:
- Knowledge of Hurricane Dynamics
- Hurricane Landfall Forecasts
- Southwest Monsoon Flow Forecasts
- Midwest Severe Storm Forecasts
- Gulf Coast Severe Weather Forecasts
- Regional and Seasonal Predictive Climate Models

- Presentation: A New ETL 449 MHz Wind Profiler for TARS

- Feb. 4, 2002

**Notes:**
The new profilers can greatly aid in NOAA’s mission to forecast severe weather events and seasonal change. 

## Requirements

- Real-time High Quality Winds
- Highest possible temporal and spatial resolution
- 4 km minimum height coverage
- User friendly Displays
- Low Cost and Reliable w/Minimal Maintenance
- Commercial Off-the-Shelf Components

- Presentation: A New ETL 449 MHz Wind Profiler for TARS

- Feb. 4, 2002

**Notes:**
Basic requirements desired by the Air Force.

## Final Design I

- ETL acts as prime integrator
- Assess and Use Latest Technology
- 449 MHz System
- to guarantee height coverage
- Almost all commercial off-the-shelf (COTS) components
- 2-kW peak power transmitter

- Presentation: A New ETL 449 MHz Wind Profiler for TARS

- Feb. 4, 2002

**Notes:**
ETL would act as system integrator, carefully selecting all major components and using as many COTS components as possible. The focus would be on reliability, maintainability, and high quality wind data. 

## Final Design II

- Vaisala/CRADA radar components
- (Receiver, Interface, Dwell Engine LAPXMTM)
- 18-element coaxial-collinear antenna
- Weber et al., Signal Processing System
- TARS Site Real-time Data Interface
- Hardware Monitor System

- Presentation: A New ETL 449 MHz Wind Profiler for TARS

- Feb. 4, 2002

**Notes:**
A CRADA (Cooperative Research and Development Agreement) was established almost 10 years ago to transfer ETL (and other local NOAA laboratory’s) radar wind profiler technology to the private sector. Many components used in the new 449 are derived from this original CRDA. Additionally, ETL derived advanced signal processing for wind profilers would be used to provide high quality winds to the flight directors.
