Uast is equipped with the complex radar system of both continuous wave pseudorandom code phase modulation and mono - pulse amplitude comparison ( crs ) , and crs measures and gets target ' s position information 在坦克超近反導(dǎo)系統(tǒng)中,裝備偽碼調(diào)相連續(xù)波與單脈沖幅度比較復(fù)合體制雷達,用于測量目標(biāo)的位置信息。
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 本文分析了幾種典型的連續(xù)波雷達信號的特性,介紹了多普勒雷達的原理和應(yīng)用;研究了偽隨機編碼信號的產(chǎn)生和數(shù)學(xué)特征,著重分析了偽碼調(diào)相連續(xù)波雷達信號的頻譜,及其在雷達測距、測速方面的應(yīng)用;研究了單脈沖幅度比較體制在雷達測角中的應(yīng)用;最后,闡述了超近反導(dǎo)系統(tǒng)中復(fù)合體制雷達的工作過程。
The autocorrelation function of the pn code is similar to that of the white noise , which has the randomicity . the pn code phase modulation fuze just works on the basis of this characteristic . the fuse , having excellent cut - off performance of the distance and strong anti - jamming capability , is one of the radio fuze of the predominant performance 偽碼引信是利用偽隨機序列的自相關(guān)函數(shù)類似于白噪聲相關(guān)函數(shù)的隨機特性而工作的,這種引信距離截止特性好,抗干擾能力強,是一種性能優(yōu)越的無線電引信。
