Hoogeboom, P. Le Chevalier, F. Otten, M.P.G. Publication year 2012 Abstract In this paper we demonstrate how Compressive Sensing (CS) can be used in pulse-Doppler radars to improve the Doppler performance while preserving range resolution. We investigate here two types of stepped frequency waveforms, the coherent frequency bursts and successive frequency ramps, which can be used for high resolution range profiling. Compared to more conventional chirps, the advantage of these waveforms would be a reduction in the receiver instantaneous bandwidth. If the Doppler performance of these waveforms can be improved, they could be used for detection and classification of respectively fast and slow moving targets. We demonstrate that applying CS in range by reducing the number of transmitted frequencies results in an increase in either Doppler resolution or Doppler unambiguous domain. Furthermore, the Doppler improvement is proportional to the range compression factor. © 2012 EUROPEAN MICROWAVE ASSOC.
