Arm的導引頭一般為單脈沖體制,因此,相干兩點源對導引頭的干擾類同於對單脈沖雷達的干擾,不同的是:對雷達的干擾都是遠場,而導引頭隨著導彈不斷接近目標,兩點源與導引頭的相對位置發生劇烈變化,由遠場變化到近場;導引頭天線口面上的合成場也發生了大的變化,相位波前的畸變產生干擾,這就是相干兩點源誘偏的基本思想。This article analyses the signal characteristics of several typical cw radars, and presents the principle and application of doppler radar. as one focal point, this article researches the generation and math characteristics of pseudorandom code modulated signal, analyses the spectrum of pseudorandom code phase modulation radar signal, and presents this kind of signal ' s application in distance and speed measurement. this article also researches the application of mono - pulse amplitude comparison radar in angle measurement finally, this article elaborates the working process of crs in uast
