Performance Evaluation Of SAR Deception Jamming

Nowadays,with the development of SAR(Synthetic Aperture Radar,SAR)deception jamming technology,the research on deception jamming is becoming a hot topic.At present,the domestic SAR deception jamming simulation is mainly based on the MATLAB platform,focusing on a variety of deception jamming algorithm.However,the performance evaluation of different SAR deception jamming algorithms,as well as the overall software joint simulation of SAR deception jamming system and SAR system has not been studied in china.Based on this,in this paper,we design a set of visual and modular performance evaluation software based on SAR deception jamming by the way of studying deception jamming method and performance evaluation of SAR,and we combine the index to evaluate the performance of SAR deception jamming.As shown below,the main work of this paper contains:1.This paper reviews the development of SAR technology and its performance evaluation by introducing the background of the topic.And then,we make a brief description of the current situation of the research on the performance evaluation of SAR deception jamming.2.We discuss the basic principle of SAR imaging by introducing the SAR two-dimensional echo signal model and SAR imaging model.Several common working modes of SAR are described.On this basis,we introduce the basic principle of SAR active deception jamming by using frequency repeater jamming as an example.And we also introduce the interface and function of the software platform of SAR deception jamming performance evaluation.This software supports C/C++ programming language modeling,generating compiled code framework automatically,and can be combined with MATLAB to simulate and other advantages.From the establishment of the basic model to the output of the simulation results of the SAR interference system,the software can integrate all the processes of modeling and simulation in a system.3.According to the squint mode of SAR,this paper studied a method of SAR deception jamming based on multiple receivers.We evaluate the range position error of the imaging of the jamming target,the azimuth position error of the imaging of the jamming target and the Doppler chirp rate error of the jamming signal.Afterwards,we use the C/C++ programming language to design the interference model on the software platform,and connect it to the SAR system in the simulation software.Simulation results verify the effectiveness of the SAR deception jamming module,which is established in the software,based on multiple receivers.The interference effect of the method is evaluated by the software simulation results combined with specific index.4.According to the side-looking mode of SAR,this paper introduces a method of SAR scattered wave deception jamming.We evaluate the range position error of the imaging of the jamming target,the azimuth position error of the imaging of the jamming target and the Doppler chirp rate error of the jamming signal.Afterwards,we use the C/C++ programming language to design the interference model on the software platform,and connect it to the SAR system in the simulation software.Simulation results verify the effectiveness of the SAR scattered wave deception jamming module which is established in the software.The interference effect of the method is evaluated by the software simulation results combined with specific index.
