[Abstract]:Synthetic aperture radar (SAR) is a high resolution imaging radar. It has the advantages of all-weather, all day, high resolution and long distance imaging. It has been widely used in both military and civil fields. With the continuous development of high resolution real-time imaging technology with unmanned aerial vehicle as a motion carrier, the real-time processing and analysis of the micro SAR with strong analysis ability is in real time. The imaging processor has become a new research hotspot. This paper focuses on the development of the main control interface and the design of the interface board of the SAR real-time imaging processor. The main control interface is directly oriented to the operating user. It has the advantages of convenient operation, simple operation and complete function. The interface board is used to communicate with the interface board through the Gigabit Ethernet interface. It is directly responsible for the function switching and system management of the SAR real-time imaging processor simulation platform. This paper first introduces the development and application of SAR real-time imaging processing technology, and then introduces the system architecture of the SAR real-time processor, including the basic requirements of the processor, the basic structure, the main control interface and the interface board function. Now and VPX high speed serial bus technology, and so on. Secondly, the realization function of the interface board is analyzed, and the overall design scheme of interface board with FPGA, DAC and VPX serial bus is introduced in detail. First, the selection of FPGA, high speed DAC and power chip is selected; then the signal generator module, DDR3 module, Ethernet connection are introduced. The design and implementation process of the basic module such as the interface module; finally, the basic function verification of the interface board, the work stability performance detection and the data interface transmission rate detection, the debugging work of the interface board are completed. Then the user requirements and the system requirements of the main control interface are analyzed, the overall framework is designed and the work flow is formulated. And the function of the system is divided into modules, the different modules do different functions, and the overall system function of the main control interface is realized through the coordination of multiple modules. At the same time, this paper uses the object-oriented programming idea, uses multi thread and double buffer technology, and finally is based on the MFC framework in the Visual Studio 2010 development environment. The design of the main control interface, and through the performance test of the function module of the main control interface, verify the completeness and stability of the overall function of the main control interface. Finally, it is the summary of this article, and the main contents of the work are summarized, and the actual work situation is linked, and some problems and shortcomings encountered in the work process are solved. A decisive approach and suggestion.
