A New Method of Moving Target Detection Based on OFDM Signal in Radar System
In recent years, with the rapid development of MIMO technology, the transmission efficiency of OFDM signal in radar system has been greatly increased, and OFDM radar has been widely studied with the good performance of OFDM signal ambiguity function. Based on the analysis of the OFDM signal frame format, this paper expounds the feasibility to detect the moving target. In this paper, we will analyze the resolution performance of the OFDM-base signal, then propose an applicable method to detect moving target based on the established echo model, and finally the simulation results and correlation analysis will be given.
