Range Imaging of Integrated Radar Communication Signal Based on OFDM

Abstract

First, based on the radar echo model of OFDM integrated radar communication signal, this article investigates the impact of target velocity and distance on the delay phase and Doppler frequency offset phase in radar echo signal by using the estimation method of Doppler frequency offset. Then, through formula derivation, the imaging principle of radar one-dimensional range image based on OFDM integrated radar communication signal is obtained, and MATLAB is used to simulate the multi-target radar one-dimensional range image of OFDM integrated signal. Finally numerical results verify that OFDM-based radar communication integrated signal can meet the design requirements of range resolution of 0.5m, and has more optimized resolution and imaging accuracy.
