Research On Radar Test And Control System Based On RTX Technology

Radar system in the military field and civilian field plays an important role andhas become a part of people’s life. As a result, radar system is progressing by thedevelopment of science and technology. The high performance of radar test systemcan help to test the performance of radar more accurately. The high real-timeperformance of radar test system for example not only needs the hardware toachieve high precision, but also needs the software to achie ve high real-timeperformance. How to design a high performance radar test and control system,become the research focus of many scholars.This article firstly analyzes the technical indicators of the hardware and thesoftware, then design the hardware in detail. Then learn the requiration of high real-time performance of the software from technical indicators. So start with softwaredevelopment platform, and research real-time and non real-time system two kindsof development platform. By study two development platform in real-time andmaneuverability on the advantages and disadvantages, and combine the advantageof the two systems, we raise the design scheme that the radar test software based onRTX technology. At last we verified the performance of the radar test and controlsystem by debugging with the whole radar test and control system.The main contents of this dissertation are listed as follows:1. Introduced the design principle of hardware of radar test system in detail,which includes auto-test equipment and communication interface card in computer.2. From the point of view of real-time performance and operability, analyzethe advantages and limitations of real-time and non real-time system. RTXextension subsystem are analyzed in detailing with the overall architecture andmemory, and in thread scheduling mechanism. Comparing the real-timeperformance of the RTX and Windows combination system and Windows system.3. Design the radar comprehensive test control system by combining in RTXand Windows system as a development environment. We design the radar test andcontrol software in form of “host-computer and console computer”. RTX extensionsubsystem works as console computer. The main function of software working inRTX extension subsystem is to control PCI-card for high real-time performancecommunications. Windows works as host-computer. The main function of software working in Windows is to respond the operation of the user. As a result, we can useone computer works like a host-computer and a console computer.4. Test the performance of the whole radar test and control system bydebugging it. We can draw a conclus ion that the radar test software is able to reachthe timing accuracy of10ms±0.5ms, and the radar test system meets all thefunction requires.
