Abstract:

A Study group was convened in the Summer of 1974 by the FAA to define a Short Range Terminal Radar SRTR to be used at high traffic density VFR airports which do not presently qualify for an ASR. The study group was comprised of representatives from the Johns Hopkins University Applied Physics Laboratory, Lincoln Laboratory, MITRE, NAFEC, AAF, AAT, ASP, AEM and ARD. The operational requirements developed for the SRTR include coverage on a small aircraft one square meter radar cross section out to 16 nautical miles up to 10,000 feet altitude and in an environment of precipitation clutter, ground clutter, angel clutter, and anomalous propagation. The MTBF goal is 500 hours and the MTTR goal is one hour. Using these operational requirements candidate radar systems were defined at three frequencies, L-band 1250 - 1350 MHz, S-band 2700 - 2900 MHz and S-band 3500 - 3700 MHz. The recommended SRTR system is the S-band system 3500 - 3700 MHz and has the following characteristics azimuth beamwidth of 3.4 deg, pulse width of 2 usecs, PRF of 2000 pps average, instrumented range of 32 nautical miles, and a data rate of 4 sec. The establishment cost in 1974 dollars for this system is 324,000. Author
