| 摘 要： | 针对传统干扰裕量法判决雷达间电磁干扰对雷达性能影响程度的不足,提出了一种基于测距误差的判决方法。建立了矩形、高斯和线性调频三种典型脉冲信号雷达测距误差计算模型,推导了测距误差与信干比的定量关系。仿真实验结果表明:随着信干比的不断增大,信号的测距误差逐渐降低,增大信号频宽也会提高测距精度。

| Abstract: | In allusion to the lack of effect of radars for radar performance on electromagnetic interference judged by conventional judging method of interference measurement, a judging method based on measuring range error was put forward in this paper. The computation models of radar range measuring error for the three representative impulse signal of rectangle,gauss and linearity frequency was established. The quantity relation of measuring range error and interference ratio （SIR） was deduced. Simulation result showed that the errors were decrease as the SIR was increased. The measuring range precision would increase when the signal bandwidth was increased. |
