元脈碼調(diào)制 - The sidelobes characters of the pn codes modulated by signals are discussed taken m-sequence and kasami sequence as examples in this dissertation . it can raise the mainlobe-sidelobes ratio when the initial phase is properly chosen . the mainlobe-sidelobes ratio can even be further improved when mismatched filters are adopted
本文第二章從國(guó)防重點(diǎn)型號(hào)裝備研制項(xiàng)目“北斗一號(hào)”用戶機(jī)的應(yīng)用需求，以m序列和kasami碼為例，研究了有符號(hào)調(diào)制的偽隨機(jī)序列的旁瓣特性，指出通過(guò)選擇合適的偽隨機(jī)序列的調(diào)制初相，可以明顯的改善主旁瓣比；失配接收可以進(jìn)一步提高主旁瓣比。 - 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(dá)信號(hào)的特性，介紹了多普勒雷達(dá)的原理和應(yīng)用；研究了偽隨機(jī)編碼信號(hào)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(dá)信號(hào)的頻譜，及其在雷達(dá)測(cè)距、測(cè)速方面的應(yīng)用；研究了單脈沖幅度比較體制在雷達(dá)測(cè)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(dá)的工作過(guò)程。 - A high-resolution method for frequency measurement is strongly introduced in the paper, which is aim at detecting the frequency of regular and binary phase coding modulated pulse signals with high frequency precision . considering the popularity of linear frequency modulated ( lfm ) signal in electronic systems, this paper then referred a radon-stft arithmetic to calculate the carry frequency of lfm signal . both of these methods referred above are implemented in the signal if detection software
針對(duì)常規(guī)脈沖調(diào)制信號(hào)和脈內(nèi)二相編碼調(diào)制信號(hào),本文提出一種高精度的數(shù)字化測(cè)頻方法,以提高信號(hào)載頻測(cè)量精度;線性調(diào)頻信號(hào)作為一種典型的非平穩(wěn)信號(hào)在各種領(lǐng)域應(yīng)用十分廣泛,但對(duì)其載頻的數(shù)字化測(cè)量比較困難,本文利用圖像處理中的radon變換與信號(hào)時(shí)頻分析中的線性變換相結(jié)合的算法來(lái)完成對(duì)其載頻的測(cè)量。 - It's difficult to see code modulated in a sentence. 用code modulated造句挺難的
