Study of Different Radar Waveform Generation Techniques for Automatic Air Target Recognition

Target recognition is the most challenging problem for missile defense. For accurate target recognition discriminant features must be extracted from the target signature. To extract suitable features an optimized waveform is needed which can be generated using pulse compression techniques. Pulse compression is a technique which can be generally used for achieving the benefits of short pulse rather than long pulse while we considering the peak power limitation. Pulse compression radar using the short pulse for detecting the target, has an advantage of achieving better range resolution. The survey presents the comparative study of different waveforms using pulse compression technique for extracting the features of target and simultaneously to achieve the high range resolution (HRRP), angular resolution, radar cross section (RCS) with the proper maintenance of SNR.
