The Design And Implementation Of Signal Acquisition And Processing System On Electromagnetic Environment Simulator Of Radar

In modern electronic warfare, electromagnetic Interference plays an important role throughout the whole process of campaign, and people realize that, only electromagnetic interference is effectively implemented can they achieve victory of battle. The issue of improving the integration combat efficiency of radar in complex electromagnetic environment is not only concerned in the R&D process of the new military equipment, but also an urgent problem of training and use of active-duty radar equipment. Therefore, the electromagnetic environment simulation of radar is a new scientific research topic and has important application prospects.This paper discussed the design and implementation of signal acquisition and processing system on electromagnetic environment simulator of radar. Firstly, the paper described the research background and current development in the domestic and foreign; secondly described the DRFM technology, including its basic structure, workflow, storage, classification, performance index and main application. Then, based on functional requirements and technical specifications, the paper put forward a plan for an overall design of the signal acquisition and processing system. On this system framework, the paper discussed the detailed circuit design of power module, high-speed acquisition module, high-speed DAC module, high speed memory module and embedded control module. The paper in detail introduced the FPGA implementation of data acquisition and storage and the study on common jamming technology, such as Doppler shift modulation in R-EW. Finally, the paper summed up the design and implementation work of signal acquisition and processing system on electromagnetic environment simulator of radar and made the forecast to the development of radar electromagnetic environment simulation technology.
