| 摘 要： | 本文用随机积分的方法引入一种合理的机载预警雷达的地(海)杂波模型.由此得出正侧面阵阵元上的时空快拍是对一低通平稳随机过程的采样.在距离环上杂波散射呈Gauss白噪声时,可知杂波过程为低通Gauss平稳随机过程.此外,还讨论了一般的杂波过程的相关函数与功率谱密度.并利用一组Mountain Top 数据对本文建立的杂波模型做了相应的验证.

| Abstract: | This paper set up a clutter model for airborne early warning radar(AEW radar)with stochastic integral.By this model we realize that when array antenna is broadside,clutter process is a low pass stationary process,and a snapshot obtained from array antenna is a sampled sequence of it.Under the hypothesis that clutter is Gaussian,we obtain the correlation function and power spectrum of clutter process.At the end of the paper,the model is verified by using the Mountain Top data. |
