Abstract


Modern radar uses pulse compression technology to effectively solve the range resolution of the contradiction between the average power . The emitted radar signal waveforms used in the design of pulse compression performance is critical . This paper describes the linear frequency modulation (LFM) signals and linear FM (NLFM) signals which are two common pulse compression signal waveform and matched filter design , focus on the NLFM linear FM signal waveform and spectral correction filter optimize the design. In NLFM signal waveform design , this paper focuses on the stay based on the principle of the window function phase reverse approach and a combination of windows in the original waveform design optimization method based on the improved optimization of pulse compression waveforms to improve performance . This article studies NLFM signal spectral correction filter optimized design, proposed combination waveform and spectrum windows optimization design method of correction filters . In addition , we propose a new window spectrum mismatch correction filter (MSFMW) algorithm , using different window function filtering the signal generation and compression are designed to take advantage of the characteristics of different window functions were adjusted pulse compression performance. And on this basis, the combination of windows and window mismatch combines two ideas put forward in the spectral mismatch correction window filtering algorithm used in combination window function method . Finally, the actual working conditions to make the corresponding simulation results prove the correctness of the above algorithm .
