The Federal Aviation Administration (FAA) is deployed a Weather Systems Processor (WSP) for the current-generation Airport Surveillance Radar-ASR-9. The WSP performs Doppler wind measurements, then automatically detects low altitude wind shear phenomena, tracks thunderstorm motion, and displays appropriate graphical and alphanumeric alerts to air traffic control (ATC) personnel. The ASR-11 differs from the ASR-9 in its use of a low peak power solid state transmitter, a pulse-compression receiver, and short (five-pulse) pulse bursts at both different pulse-repetion frequencies (PRF) and different RF frequencies. In this report, the authors assess the technical and operational issues associated with adding a WSP to the ASR-11. A benefits assessment was performed to evaluate the operational requirement for an ASR-11 based WSP. The authors estimate that the value to the public and airline industry of reductions in aircraft delay, and avoidance of unnecessary diversions, would be in excess of eight million dollars per year tallied across 18 of the larger ASR-11 equipped airports.
