FPGA Software Design For Reconnaissance And Jamming Integration Processor

In the field of missile penetration,the traditional missile-borne jammers are often difficult to obtain direction of arrival of radar radiation source,it needs the guidance by specialized electronic reconnaissance receiver.With the development of miniaturization design technology for jammers,it is necessary to integrate the reconnaissance and jamming,that is,integrate the direction-finding function in the jammer and have a variety of jamming mode to deal with the threat from a variety of radar.In this paper,the key technology in the integrated design of reconnaissance and jamming is studied and simulated,and the software algorithm is designed and implemented in the FPGA hardware platform of the jamming machine,the main research work of this paper is as follows:.Firstly,based on the integrated design requirements of the jammer,an integrated device scheme based on DRFM(digital radio frequency memory)is proposed.The scheme integrates the direction finding and jamming function,and achieves the miniaturized design requirements.Secondly,for the radar signal reconnaissance technique,the principle of radar signal parameter measurement and the direction finding of the phase interferometer based on virtual baseline is analyzed in detail.The method solves the problem of solving the wideband direction finding problem in the case of antenna installation space limitation.For the radar jamming technique,the intermittent sampling cycle propagation jamming method based on the delay superposition is proposed by analyzing the principle of intermittent uniform sampling and nonuniform sampling repeater jamming and intermittent sampling cyclic forwarding repeater jamming.By setting different parameters,this method can generate dense false target suppression jamming and false target deception jamming.Then in the FPGA hardware processing platform,the reconnaissance and jamming module programs are designed and simulated,and the module function is verified.Finally,the hardware system test,test includes the function of the module and some of the performance,the test results show that the device complete the reconnaissance and jamming functions,and achieve the desired performance.This integrated device enhances the reconnaissance capability of the jammers,and it can confront various systems of radar,that makes it with engineering application value.
