| 摘 要： | 本文建立了双基地机载预警雷达空时二维杂波模型,其中考虑了双基地雷达的几何配置、雷达的系统参数、各种误差及距离模糊等实际因素对杂波谱的影响.基于该模型分析了杂波特性,并计算了杂波的空时二维似然谱,结果表明所建杂波模型是合理的.该模型是研究双基地机载预警雷达杂波抑制与空时自适应处理技术的基础.

| Abstract: | This paper sets up a two-dimensional space time clutter model for bistatic airborne early warning(AEW) radar.The impact on clutter spectrum of the practical factors such as the geometric configurations of bistatic radar,the parameters of radar system,range ambiguity and all kinds of errors etc.is considered in the model.The clutter characteristics is analyzed based on this model. The rationality of the clutter model is illustrated by computing two dimensional space-time likelihood spectra.This model can be used for studying the clutter suppression and STAP techniques for bistatic AEW radar. |
