Cooperative Scatter-wave Jamming of Multi-jammer Against SAR Dual-channel Cancellation
摘要
Abstract
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.关键词
