高斯频谱的非线性调频信号脉压性能分析

Analysis of NLFM Signal With Gaussian Spectrum

根据逗留相位原理,利用计算机仿真画出基于高斯频谱的非线性调频信号的时频域波形,并对该信号的脉压性能作了分析.研究表明,这种信号的主副瓣比远比线性调频信号要高,可达48.8dB.

Based on the theory of phase-staying, this article presents the waveforms with Guassian spectrum of NLFM signal in the time and frequency domain, and analyzed the characterstics of pulse compression in the signal. It shows that the ratio of mainlobe to sidelobe from the NLFM signal is better than that of the LFM signal, which can be up to 48.8dB.
