针对SAR双通道对消的多站协同散射波干扰
|
摘要
合成孔径雷达(SAR)双通道对消技术可有效抑制单站散射波干扰,因此,文中提出对抗双通道对消系统的多站协同散射波干扰方法,结合补偿相位搜索和对消流程分别分析了多站同时工作和多站分时交替工作的干扰效果。沿方位向部署的多个干扰站可破坏SAR各通道接收干扰信号的原有相位关系,从而严重影响相位搜索结果和场景成像。理论分析与实验结果表明:多散射波干扰站同时工作时,可在对消成像中形成多个无法被消除的虚假散射场景,并伴随部分真实场景信息损失;多站分时交替工作时,可使得场景对消成像出现类似噪声的明暗斑,并且三站分时干扰效果优于双站。
Synthetic aperture radar(SAR) dual-channel cancellation technique can suppress the scatter-wave jamming of single jammer effectively, so the cooperative scatter-wave jamming method of multi-jammer against dual-channel cancellation system is put forward, and the jamming effect of multi-jammer simultaneous working and time-shared alternate working is analyzed upon compensation phase searching and cancellation process. Multi-jammer deployed along azimuth can destroy the original phase relationship of jamming signals received by different SAR channels, and produce bad effects on phase searching result and scene imaging. Theoretical analysis and experiment result show that: multi-jammer simultaneous working can produce multi-false scattering scenes that cannot be eliminated in the cancellation imaging, along with loss of scene information; multi-jammer time-shared alternate working can produce chaotic dark and bright speckles in the scene cancellation imaging, and three-jammer time-shared jamming effect is better than that of dual-jammer.
