Abstract : A study was performed to develop and evaluate techniques for suppressing false alarms in air-defense radars. The study included analytical performance investigations for a number of candidate signal processor architectures and cost/performance tradeoffs for the leading candidates. Detail analyses of processor performance were conducted as a function of parameters such as number of target samples coherently processed, input signal-to-clutter ratio, input signal-to-noise ratio, and presence or absence of Moving-Target-Indicator canceller processing. Detailed block diagrams were generated and estimates made of such cost-influencing factors as the number of components/cards required by each approach and software requirements, as a function of system specifications such as number of instrumented range cells and number of samples coherently processed.
