Resumen:

Real-time implementation of electronic warfare digital receivers is strongly constrained by the limited operation rate of data processing blocks. This problem can be partially overcome by using monobit DFT instead of a conventional DFT algorithm. The main disadvantage of the monobit approximation lies in the increase of false alarm probability (P/sub FA/). An alternative data processing block based on a filter bank is proposed. This is achieved by means of a genetic algorithm optimization of the monobit DFT filter bank. P/sub D/-P/sub FA/ (detection probability - false alarm probability) performance of the digital receiver using the optimized filter bank is also discussed.
