Design Of A General-purpose Auto Test System For Airborne Radar

Airborne radar is a system integrated with various high technologies. Its signal form:from digital,analog,video image,RF to microwave signal; Its control:various general-purpose and self-defining bus,various open-loop and closed-loop signal,etc;So,MTBF of radar is relative low compared with other avionics.To automatically test technique performance of radars not only ensuresthe manufacture quality of radars but also provides the essential quantitative and qualitative information for maintenance, fault detection and diagnosis.The automatic test is the major path to measure whether the radar normally functions or not and to localize the faults.Firstly this dissertation described the development,composition and structure model of Automatic Test System,compare and discuss the bus technology,and analysed the test requirements for Airborne radar.From them,we put forward of design of the ATS(Atomatic Test System).Detailed discussions list as follows:1.Based on VXI(VME Extended to Instrumentation)and GPIB (General Purpose Interface Bus)technique,how to build and realize the radar automatic test system.2.Design of Receiver of test adapter interface(RCV)and TUA(Test Unit Adapter).3.The structure,constitute,hiberarchy and function of the test software,based on PAWS(professional ATLAS work station).The Airborne radar general-purpose automatic test system introduced in this dissertation has passed the state inspection and qualification. Qualification and utilization results demonstrATS that the efficient and advance.
