合成孔径雷达电子对抗技术综述

在介绍合成孔径雷达干扰(SAR)干扰对抗技术研究现状的同时,概述了与之密不可分的SAR系统性能、抗干扰措施以及干扰效果评估方面的研究现状.分传统性干扰方法和特色干扰方法,列出了当前典型的SAR干扰样式;重点讲述了SAR干扰技术的发展历程;分析归纳出SAR对抗技术的发展趋势以及存在的问题.为有效干扰SAR,必需从非相干干扰走向相干干扰、从简单噪声干扰走向复杂样式调制干扰、从单一干扰手段走向复合、多样的智能干扰以及从静止目标干扰走向运动目标干扰.

Review of Synthetic Aperture Radar Electronic Countermeasures

Besides the introduction of Synthetic Aperture Radar (SAR) Electronic Countermeasures ( ECM), the closely related aspects of SAR systems, Electronic Counter-Countermeasures (ECCM) and the jamming evaluation are also reviewed as well. The typi-cal jamming techniques are divided into two types as the traditional jamming methods and peculiar jamming methods, and are displayed one by one in detail. The development history of SAR jamming techniques are provided, where the development trend and the existing problems are induced. To make SAR ECM more effective, the jamming techniques trend towards coherent jamming complicatedly modu-lated jamming, multiple various jamming, and moving target jamming.
