Abstract(in English) The Doppler estimation by Pulse-Doppler Radar is realized by measuring phase shift in pulse-train, and this technique is often used in Frequency Modulated-Continuous Wave (FM-CW) Radar. However, the visiblevelocity range is limited by Pulse Repetition Interval (PRI) and fast moving targets exceeded the visible range isestimated with large error because of aliasing problem. When an observation time is sufficiently long, the velocitycan be easily derived from range estimation results between two points. However, if the observation time is not solong, the PRI should be short enough to prevent aliasing that is often hard to realize due to hardware limitation atthis moment. In this paper, we consider a correction of the wrapped velocity estimation result. We define a modevector to derive the number of wraps by using both fast-time (Range domain) and slow-time (Doppler domain). Weshow results of appliying Multiple Signal Classification (MUSIC) algorithm to both simulation and experimentaldata, consider the efficancy.
