Investigation on Countermeasure against InSAR Dual-channel Cancellation Technique with Multi-antenna Jammer
-
摘要: 干擾機(jī)運(yùn)動(dòng)能給雙通道干擾對(duì)消帶來困難，但連續(xù)運(yùn)動(dòng)的干擾機(jī)只在一定范圍內(nèi)有較好的干擾效果。旋轉(zhuǎn)干擾機(jī)具有運(yùn)動(dòng)的重復(fù)性，該文分析了旋轉(zhuǎn)運(yùn)動(dòng)的干擾機(jī)對(duì)InSAR雙通道干擾對(duì)消的影響，針對(duì)旋臂過長(zhǎng)不易實(shí)現(xiàn)的問題，提出用分布式的多干擾發(fā)射天線通過分時(shí)發(fā)射模擬旋轉(zhuǎn)干擾機(jī)的方法，仿真結(jié)果證明了該方法的有效性。

Abstract: Jammer motion brings trouble to the dual-channel cancellation, but the good result is restricted to a limited range. The rotation motion of a jammer is periodic, the effect of rotating jammer on InSAR dual-channel cancellation is studied in this paper. Since the rotating arm is too long to put into practice, an alternative method using multi-antenna jammer is presented, the antennas emit interference signal on a time division basis. Simulation result shows that the proposed method is effective. -
