干扰合成孔径雷达的统一方程

合成孔径雷达(SAR)是当前的一种新型雷达体制,它既能测定目标的座标位置又能对目标成像,不论在军用还是在民用都有广泛的应用和广阔的发展前景,当然也就成了雷达干扰研究的重点对象。我们应用了几年的时间,分析了对SAR的干扰原理;推导出对SAR的干扰方程;做了多种仿真干扰试验,室内小功率模拟干扰试验和实际飞行干扰试验,获得大量干扰数据和干扰图像,证明了推导的干扰方程的正确性。还证明了常规脉冲雷达的干扰方程与SAR的干扰方程可以统一成一种方程。只是在计算干扰等效功率时,取不同的干扰压制系数即可。

Unified jamming equation of synthetic aperture radar

Synthetic aperture radar(SAR) is a kind of new radar system which can measures a target's coordinate location and generates its image.This radar has broad applications and development prospects in both civil and military aspects.Certainly it is a major object in the area of radar jamming research area.In the past several years,we analyzed the SAR jamming principles,derived a SAR jamming equation,carried out a variety of simulation experiments,and obtained a lot of jamming data and jamming pictures through indoor small power jamming test and actual flying tests.All this has proved the validity of the derived SAR jamming equation.We also proved that the conventional radar jamming equation and the SAR jamming equation can be unified into one common equation.When computing their equivalent jamming powers,only different jamming suppression coefficients should be used.
