MTI IMPROVEMENT FACTOR ENHANCEMENT AND RADAR SYSTEMS PERFORMANCE BY USING DOUBLE –DELAY FILTER AT THREE –PERIOD STAGGERED
Staggering the pulse repetition intervals is widely used to alleviate the blind speed problem in Moving Target Indication (MTI) radar systems. It is possible to increase the first blind speed on the order of ten solds using non-uniform sampling. Improvement in blind speed results in passband fluctuations that may degrade the detection performance for particular Doppler frequencies. Therefore, it is essential to design MTI filters with non-uniform interpulse periods with minimum passband ripples, sufficient clutter attenuation, and good range and blind velocity performance.
