Motion compensation for modulated freqeuency stepped pulse

The modulated frequency stepped pulse radar signal uses chirp as subpulse of a frequency stepped pulse train. One of the key problems of the signal is target motion compensation. This paper analyses the influence of target motion, then discuses the compensation method based on the analysis. A compensation method introduced to correct the envelop shift. The doppler processing between frequency stepped bursts is a method used in velocity measure, but the unambiguous doppler range is small. A new method is presented to improve it and resolve the problem.
