VPX platform constructs comprehensive radio frequency system

Abstract

The invention provides a VPX platform architecture comprehensive radio frequency system, and aims to provide an extensible, reconfigurable and upgradable comprehensive radio frequency system. The method is realized through the following technical scheme: an integrated channel unit completes mutual conversion of an analog radio frequency signal and an analog intermediate frequency signal; the comprehensive sampling unit converts the analog intermediate frequency signal output by the comprehensive channel unit into a digital intermediate frequency signal through ADC sampling, and sends the digital intermediate frequency signal to the comprehensive signal processing unit through a bus; the comprehensive signal processing unit receives the digital intermediate frequency signal of the comprehensive sampling unit through a RapidIO interface, completes digital signal processing of the digital intermediate frequency signal, sends the coded and modulated digital intermediate frequency signal tothe comprehensive sampling unit to be converted into an analog intermediate frequency signal, and sends the analog intermediate frequency signal to the comprehensive channel unit; the comprehensive sampling unit selects different ports to receive and transmit digital intermediate frequency signals, and random combination between radio frequency analog signals and digital processing resources is achieved.

Description

Problems solved by technology

[0002] With the rapid development of wireless measurement and control technology, the continuous enrichment and improvement of aerospace measurement and control, navigation and other functions, while improving the reliability of measurement and control, it also brings an increase in the number of radio frequency equipment, complex electromagnetic environment between equipment, large system volume, and testing operation and maintenance. Difficulties such as heavy workload and high demand for personnel

This kind of distributed radio frequency sensor has independent functions, each function has its own independent supporting equipment, the degree of modularization is low, the weight and volume are relatively large, and the cost is high, and the integration is relatively poor, so it is difficult to upgrade or improve it. Can not adapt to the current trend of rapid development of information technology
