| 摘 要： | 描述了一种用于机载雷达测试的中频地杂波信号模拟器,其特点是杂波信号功率谱形状十分接近理想的高斯型,其幅度分布和相位分布也同时接近真实的地杂波分布。该设备采用了双通道独立产生高斯过程的方法,保证了输出杂波的幅相随机性。为了模拟载机的运动和天线扫描引起的杂波中心频率及带宽的变化,杂波的中心频率实时可调,杂波的带宽也可以在很宽的范围内调定。最后,本文给出了该设备的性能指标及测试结果。

| Abstract: | This paper describes an intermediate frequency(IF)ground cluttersimulater for testing airborne radars.The output spectrum of this simulator is very closedto the ideal Gaussian form and distributions of the clutter amplitude and phase are alsovery closed to practical ones.The simulator uses two channels generating independentGaussian processes to get the randomness of clutter's amplitudes and phases.In order tosimulate the variation of central frequency and bandwidth of the clutter caused by theairplane motion and the a nna scanning,the central frequency of the clutter is adjusta-ble in real time and the bandwidth of the clutter is also adjustable in a wide range.Finally,performances and test results of the simulator are given. |
