基于Hamming窗NLFM信号抗有源噪声干扰分析

Analysis of Anti-active Noise Jamming of Hamming Window-based NLFM Signal

为了研究NLFM信号的抗干扰问题,基于Hamming窗NLFM信号,建立雷达脉压系统仿真模型.通过仿真实验,比较了在不同的有源噪声干扰样式下该NLFM脉冲压缩滤波器的抗干扰性能,分析了噪声干扰对脉压输出主瓣宽度的影响,得出了相应结论.

To study anti-jamming of NLFM signal the simulation model of radar pulse compression system was set up based on NLFM signal of Hamming window function. By simulation, the performances on anti-jamming of the NLFM pulse compression filter were compared in terms of various active noise jamming environment. And the influence of noise jamming on main lobe width of output pulse was analyzed, by which the related conclusions were drawn.
