Wavelet-based radar waveform for moving targets detection

In a previous paper by the authors, a wavelet-based waveform (WBW) is described which can suppress range sidelobes for static targets effectively. In this paper, we describe the use of WBW in speed detection via Doppler frequency. We compare WBW with conventional waveform using linear frequency modulation (LFM) for both range and speed detections. Analysis and simulation results show that WBW achieves higher resolution in both range and speed detections over LFM. Further study shows that WBW can be applied in SAR to acquire high resolution image.
