摘要
简述了单脉冲雷达角跟踪系统的测角原理,提出并分析了对单脉冲雷达进行角度欺骗的相干两点源干扰。仿真表明,相干两点源干扰可以有效地诱偏雷达天线,使其指向偏离干扰源的物理中心。当两干扰源幅度相等、相位差为180°时该诱偏角度最大。
This paper briefly describes the angle principle of monopulse radar＇ s angle tracking system, presents a method of angle deception to monopulse radar, that＇s coherent dual-source interference, and anlyzes its interference mechanism. Results of simulation proved that, the coherent dual-source interference can effectively tempt the radar＇ s antenna to deviate from the physical center of dual sources. When the dual sources are with equal range and their phase error is 180°, the removed angle is maximal.
