Abstract
Stepped frequency radars attract many attentions due to their high range resolution.
Conventional processing technique in these radars is based on the IDFT. In detecting moving
targets, the IDFT has the problems of range shifting and range spreading, which result in
degrading target amplitude, loss of range accuracy and range resolution. To overcome these
problems, the velocity compensation method is used. Since the target velocity is unknown, one
should compensate the received signal with all possible velocities and choose the one with the
highest and sharpest IDFT output. In this paper, by using the compressive sensing based
algorithms, a new method for determining the range and the velocity of moving targets in the
stepped frequency radar is proposed. The results show that the proposed method does not have
any problem with range shifting and range spreading, and has a better performance compared
with other methods in literature. Coherent processing concept is also investigated. Simulations
show that using the coherent processing, the performance of compressive sensing based radar
detectors is considerably improved.
