Abstract

Signal processing algorithms are widely used in various applications to find position, range and velocity of moving objects. Signal processor part of radar has to perform heavy computations. The time required to localize the target is also critical for surveillance. When target is approaching the radar, detection needs to be faster. A radar signal processor is proposed which is capable of finding range and Doppler with variable processing times for two set of target ranges. The proposed algorithm saves processing time for short range set by reducing the computations involved in FFT stage of conventional two dimensional algorithm. For longer range set, the conventional two dimensional algorithm is used for achieving higher processing gain. It is shown that the modified approach saves much time as compared to the conventional algorithm. The proposed algorithm with reduced processing time can also be useful for long range set if high gain transmitter or better LNA is used at the receiv...
