Abstract

Abstract

Phase-Coded Orthogonal Frequency Division Multiplexing (PC-OFDM) radar has drawn wide attention in high resolution radar application. This kind of radar signal transmits orthogonal sub-carriers phase-modulated by specific sequences and has range and Doppler high resolution at the same time. Considering its sensitivity to Doppler offset, this paper derives the pulse compression method of PC-OFDM radar, and based on Cyclic Prefix (CP), a Doppler offset estimation and compensation algorithm is proposed. Several simulations verify the effectiveness of the method in improving High Resolution Range Profile (HRRP) with Doppler offset.
