Abstract
Range and velocity estimation of moving targets using conventional steppedfrequencypulse radar may suffer from the range-Doppler coupling and the phasewrapping. To overcome these problems, this paper presents a new radar waveform namedmultiple stepped-frequency pulse trains and proposes a new algorithm. It is shown that byusing multiple stepped-frequency pulse trains and the robust phase unwrapping theorem(RPUT), both of the range-Doppler coupling and the phase wrapping can be robustlyresolved, and accordingly, the range and the velocity of a moving target can be accuratelyestimated.

Summary
Range and velocity estimation of moving targets using high range resolution radar is a topic of great interest. To achieve this goal, there are two problems to be considered. Stepped-frequency pulse train processing is a well-known technique to obtain high range resolution without the requirement of wide instantaneous bandwidth [1,2,3,4,5,6,7], and it is adopted in this paper.
