Abstract

Due to good balance among spectrum efficiency, ambiguity function and peak-to-mean envelope power ratio (PMEPR), wideband Multi-Carrier Phase-Coded (MCPC) radar has caught much attention from researchers recently. Based on separation of sub carriers from multi-frequency structure, this paper provides velocity estimation method for such radar signal. After detecting the peek Doppler spectrum of each sub carrier, the unambiguous velocity can be obtained by Least-Squared (LS) algorithm. The simulation results show that these methods can estimate the velocity of fast-moving target efficiently and guarantee the accuracy against low SNR.
