合成孔径激光雷达电子对抗措施分析

The Analysis of Electronic Countermeasures for SAL

对合成孔径激光雷达(Synthetic Aperture Ladar,SAL)的电子对抗问题进行了研究。由于SAL与SAR(Synthetic Aperture Radar)同中有异,因此针对SAR电子对抗措施对于SAL的适用性问题进行了研究。具体研究了噪声遮盖干扰、有源欺骗干扰、散射干扰等SAR有源干扰技术在SAL电子对抗中的机遇和挑战。给出了一些研究结果,提出了适用于SAL的伴飞式重点目标散射干扰方案。

The problem of ECM for synthetic aperture(imaging) Ladar(SAL,or SAIL) is studied in this paper.Although SAL is similar with SAR(synthetic aperture Radar),there are still some differences between them due to the different wave bands they used.So the methods of jamming for SAR are not always perfect for SAL.Special attention is carried out on these active jamming techniques for SAL,including noise barrage jamming,active deception jamming and scattering jamming.Several conclusions are obtained.A method of tracing-flight-scattering-jamming based on key target protection is presented.
