摘要
讨论了无线电引信遭遇箔条云时 ,箔条云反射信号的特性 .在箔条云远区 ,根据箔条云回波信号的时域特性 ,推导出回波信号的频谱特性 .在箔条云近区 ,将箔条云看成一个集合目标 ,推导出近区箔条云的雷达截面积和反射功率 .对于箔条云干扰和无线电引信的抗干扰研究具有一定的作用 .
Some distributions of reflecting sig nal of chaff are discussed when radio fuzes are jammed by chaff. At far field, t ime-area distribution is discussed, and frequency distribution has been calcula ted. At near field, the chaff cloud is thought an aggregate target, and chaff is thought a scattered element, therefore scattering of chaff cloud is thought int egral of all scattered elements. RCS and reflecting-power of near field have ca lculated. The results are useful for research of jamming and antijamming of chaf f cloud to radio fuzes.
