As compared to the commonly used constant frequency radar waveforms, the stepped-frequency waveform can achieve high range resolution while still retaining the advantages of lower instantaneous receiver bandwidth and lower analog-to-digital sampling rate. However, the relative radial motion between the target and the stepped-frequency radar will result in performance degradations, such as range error, loss in signal-to-noise ratio, and degraded range resolution. The solution to this problem is to apply velocity compensation to the received signal, which can eliminate the degradations due to Doppler effects. Three velocity compensation schemes for the detection of a moving target in clutter are designed, discussed, and compared in this thesis. Also, a simulation is presented to verify the concepts, and simulation results are compared and discussed.
