卫星制导弹箭抗干扰性能试验方法研究

Method of anti-jamming performance test for missile guided by satellite

由于卫星信号容易受到电磁干扰影响,因此在卫星制导体制弹箭研制阶段过程中必须要通过配置不同的卫星干扰环境条件,进行抗干扰性能评估的试验。针对卫星制导弹箭的抗干扰性能需求,文中从试验成本及测试结果的可信度方面出发,分析了卫星抗干扰性能试验的内场、外场试验方法,比对了压制干扰与欺骗干扰的作用机理,提出了基于抗压制干扰方式的内场微波暗室的试验方案。随后以北斗卫星的B3频段参数为主,对干扰类型、干扰标定、干扰源布局方式的干扰源试验参数进行了设计。最后,确定单干扰源、三干扰源的抗干扰试验方法,并对干扰天线角度与转台工作情况进行了详细规定,确保能够通过有限的抗干扰试验真实评估卫星制导组件在电磁环境中运行的性能情况。

Because the satellite signals are susceptible to electromagnetic interference,the test of anti-jamming performance evaluation of the missile must be conducted under different satellite interference environmental conditions during the development stage of the missile with satellite guidance system.According to the requirements of anti-jamming performance of the missile guided by satellite,the infield and outfield test methods of satellite anti-jamming performance test are analyzed,the action mechanisms of suppression jamming and deception jamming are contrasted,and a test scheme of infield microwave anechoic chamber based on anti-suppression jamming mode is put forward in the perspective of test cost and reliability of test results.Subsequently,on the basis of B3 frequency band parameters of Beidou satellite,the interference source test parameters of interference type,interference calibration and interference source layout manner are designed.The anti-jamming test methods against single interference source and triple interference sources are designed,and the angle of the jamming antenna and the working condition of the rotary platform are specified in detail,so as to ensure that the performance of the satellite guidance module in the electromagnetic environment can be truly evaluated in the limited anti-jamming test.
