摘要
基于成对回波理论,针对波导色散对宽带信号脉压的影响进行了理论分析,推导出了具体的数学表达式.并针对宽带LFM信号进行了仿真实验.理论分析和仿真表明,波导色散会使宽带信号的脉压波形主瓣展宽,旁瓣幅度升高和积分旁瓣比变大.
Based on the paired-echo theory, me effect of waveguide dispersion on performance of the wideband pulse compression was analyzed and the corresponding expression derived. The simulation experiment was performed with LFM signal. Theoretical research and simulation results show that the waveguide dispersion results in the wider main-lobe of pulse compressed wideband signal while the amplitude of the side-lobe is higher and the ISLR greater.
