Adaptive Pulse Regulations to Achieve High Range Resolution within the Unambiguous Window

In this article, we consider a kind of high resolution radar system with adaptive pulse adjustment for target detection and locating. There exist a trade-off between the ambiguity range distance and the resolution, we adaptively regulate the carrier spacing to make the ambiguity range window large enough to contain all target extent with a specified DFT size. Doppler shift and the target moving velocity is considered for target range resolution. We also present the critical value for each sub-pulse sequence to quickly obtain all scatters. The waveform at the receiver side after low pass filter and IFFT procedure is shown to illustrate the effectiveness of the proposed approach.
