Waveform Libraries of Radar

The flexibility in the selection of waveforms indicates the performance of Radio Detection and Ranging(RADAR) system. These waveforms help in separation and identification of two targets, which are closely spaced in range or traveling near to each other by the the same speed. So,the waveforms should be checked for determination of its resolution and ambiguity in both the range and speed. In Radar, the range is measured using delay and speed by using the doppler shift. In this paper, the rotatable waveforms are generated with help of Fractional Fourier Transform(FRFT),and by using Frank code/Barker code. Different parameters such as delay resolution, doppler resolution are compared using an ambiguity function.
