摘要：Owing to the problems such as the design of radar waveform using traditional method cannot be promptly applied in radar system, and to the difficulty and high cost in acquiring experimental data, we propose a simulation method of semi-measured data of radar echo based on measured echo data of conventional active radar. Specifically, we first design the radar waveform, and then conduct pulse compression and convolution algorithm to obtain the radar echo's semi-measured data combined with the newly designed waveform and measured echo data. Taking chaotic modulation multicarrier phase coded signal as an example, the radar echo's semi-measured data is simulated, and the signal processing and target detection are completed. The proposed method of semi-measured radar echo can overcome the inherent deficit induced by sophisticated mathematical simulation and modeling in generating radar echoes approximating to the real complex environment. In addition, our method provides effective data support for the design, analysis and performance evaluation of radar systems, and is convenient for rapid demonstration and exploration on the advantages of the designed radar waveform.
