| 摘 要： | 地海杂波对采用前视以及下视成像的机载、弹载雷达具有十分重要的影响,对港口成像,会同时受到地杂波和海杂波的影响。文章提出复合场景杂波的后向散射系数模型,推导了复合场景杂波的幅度分布公式,并对由对数正态杂波与韦伯杂波组成的复合杂波分布进行了仿真。仿真中,地海杂波功率比选取了0.001到50之间的一系列典型值,并将不同情况下复合杂波的幅度分布与单一对数正态分布模型和Weibull分布模型得到的杂波分布进行了比较,结果表明二者的复合杂波分布依赖于二者的功率比。

| Abstract: | The land clutter and sea clutter seriously affect the air-borne and missile-borne radar in the forward-looking and down-looking modes.The radar imaging of the target in the port was affected by the clutter from the sea and coastal land.A new backscattering coefficient model of the compound environment is proposed in this paper.The amplitude distribution of composite environment's clutter is deduced in the paper.Taking log-normal distribution and Weibull distribution clutter as sample,the composite distribut... |
