振幅相位误差对雷达性能的影响

The effect of the amplitude and phase errors on radar performance

从工程应用角度出发,分析了振幅误差和相位误差对雷达性能的影响。为了简化起见,只考虑地杂波和单频干扰,且不考虑接收机的热噪声,文中讨论了单脉冲测角精度,时间域中滤波器抑制杂波的能力和空间域中滤波器抑制有源干扰的能力等6个有关雷达设计中的具体问题,结论简明,并给出了曲线提供参考。

This paper analyzes the effect of the amplitude and phase errors on radar performance from the viewpoint of engineering applications. For simplicity, the thermal noise of receiver is neglected and the ground clutter and the interference with dot frequency are only considered. The specific probolems dealing with the accuracy of direction finding with monopulse technique and the capacities of clutter and jammer rejection of the filters in time-domain and space-domain are discussed. Some useful results are presented in the paper.
