Airborne Sar Antenna Platform Test Data Processing Module And Simulation Database

This thesis focuses on the project automation test system based on virtual instrument for Aircraft-borne SAR Antenna Stabile platform which is supported by innovation fund of China Academia of Sciences. Based on the analysis of existing automation test system for aircraft-borne SAR antenna stabile platform, pointed out that this system needs further improvement in the test reliability and the simulation test environment.In order to strengthen the reliability of the test system and improve original platform test-data processing module based on the desktop PCI bus technology, a platform test-data processing module based on PXI bus technology was designed and implemented, and the module system structure, the processing for accepting of asynchronous serial data, the DSP program designing and writing were elaborated with emphasis. And an independent WDM driver was designed for this module.This thesis researched flight characteristics for the Aircraft-borne SAR, and pointed out that the inertial-navigation data can reflect the change of flight attitude in the case of radar imaging completely, and first time a new method that establishing a simulation database using flying angle data was put forward. The data in this database was processed and then used to control the moving of the two-dimensional electrical turntable, then the turntable simulated real angle-moving of aircraft, and provided a controllable and lifelike test environment for the turntable test.This article elaborated designing of the simulation database in detail, including database access technology ADO, designing of various tables in database, and simultaneously designing of application program for the simulation database was explained with emphasis. VC and Matlab mixing technology based on COM module technology, angle-data filtering, angle data analysis which were used in programming of database maintenance software, and the virtual instrument software program technology, data interpolation, software programming for turntable control which...
