基于CP-OFDM发射波形的目标检测算法研究

This project mainly deals with the problem of target detection based on the cyclic prefix (CP) orthogonal frequency-division multiplexing (OFDM) transmitted waveform. The CP-OFDM transmitted waveform based target detection theory can be established and improved by studying the following fundamental problems: the CP-OFDM transmitted waveform based pulse compression and pulse integration algorithms, the target detection algorithm by jointly pulse and multi-pulses processing, the CP-OFDM waveform optimal design criterion, the adaptive CP-OFDM waveform design method. We will solve the key technologies, and propose a CP-OFDM waveform design based target detection signal processing method. Besides, simulation experiments will be used to validate the presented the theory results and technological achievements. The research of this project is of great significance, since it can provide the theoretical and technical basis for the applications of CP-OFDM waveform design in real radar systems. Moreover, the theoretical results can also be utilized in other research fields such as target detection for MIMO radar and automotive radar.
