The Analysis of Influence of the Antenna Sidelobe on the

用计算机仿真和实验测试数据分析了天线副瓣对机载脉冲多普勒雷达地杂波的影响。分析结果表明天线远区副瓣对雷达地杂波的影响较大 。

The influence of the antenna sidelobe on the ground clutter received by airborne pulsed doppler radar is analyzed by computer simulation and experimental data. The results shows that the sidelobe in the far region has greater impact on the ground clutter, so the emphasis should be placed to reduce the far field sidelobe of antenna in the radar system design.
