The thesis analyses and emulates the signal processing arithmetic of monitoring receiver in detail , particularly in the performance and improvement of spectrum analysis arithmetic 本文對監(jiān)測接收機(jī)的信號處理算法進(jìn)行了詳細(xì)的分析和仿真,尤其對頻譜分析的算法性能和改進(jìn)方法作了深入研究。
Last , the thesis does a research on the application in the system of visa , then analyzes the program control method of vxiplug & play system and the software architecture of monitoring receiver 最后,本文研究了visa在本系統(tǒng)中的應(yīng)用,分析了vxi即插即用系統(tǒng)編程控制方法和監(jiān)測接收機(jī)的軟件結(jié)構(gòu)。
The author brings forward a scheme of vxi bus based broadband digitalize monitoring receiver , on the basis of his deep research on vxi bus technology and visual instrument software architecture 本文作者在深入研究vxi總線技術(shù)和虛擬儀器軟件體系的基礎(chǔ)上,提出了vxi總線平臺的寬帶數(shù)字化監(jiān)測接收機(jī)方案。
A series of new technologies such as software radio , vxibus , dsp , virtual instrument , measurement and instrument , interface technology apply to the broadband monitoring receiver related to this paper . its research not only satisfies the needs of our radio monitoring branch , national defence branch but also breaks the technology blockage 本文涉及的寬帶監(jiān)測接收機(jī)將軟件無線電技術(shù)、 vxi總線技術(shù)、 dsp技術(shù)、智能儀器技術(shù)、測控技術(shù)、接口技術(shù)等一系列正在蓬勃發(fā)展的新技術(shù)緊密結(jié)合起來,它的研究不僅可以滿足我國無線電監(jiān)測、國防、安全等部門的實(shí)際需要,還可以打破少數(shù)發(fā)達(dá)國家對我國的技術(shù)封鎖,為我國的無線電監(jiān)測、國防、安全等部門的設(shè)備建設(shè)做出貢獻(xiàn)。
In recent years , radio technology has developed very quickly in our country . however , a radio monitoring receiver with broad frequency scale ( 20 - 3000 mhz ) , high scanning rate ( above 1ghz / s ) and whole spectrum real - time display has not developed . some imported monitoring receivers with broad frequency scale can only scan slowly and could n ' t meet actual needs . not only these imported receivers " price is high but also those developed countries usually limit the quantities of imported receivers and related technology is not open 近年來我國無線電技術(shù)水平已經(jīng)有了很大發(fā)展和進(jìn)步,但對于頻率覆蓋范圍寬( 20 - 3000mhz ) 、掃描速度快( 1ghz / s以上)并具備快速全頻段實(shí)時頻譜顯示和記錄的無線電監(jiān)測接收設(shè)備,目前我國尚不能生產(chǎn),國內(nèi)現(xiàn)在已經(jīng)進(jìn)口的寬頻段監(jiān)測接收機(jī)一般也只能進(jìn)行低速掃描,無法滿足實(shí)際的需要。
