Development Of Forward-Looking Super-Resolution Imaging Method And Simulation Software For Airborne Radar

Airborne radar front super resolution imaging technology is widely used in forwardlooking reconnaissance,supplies dropped,such as civil and military fields,however,the existing various forward-looking super resolution imaging method widespread promotion limited resolution,and large computation and simulation of radar data at the same time to rely too much on Matlab simulation software,poor user experience and complex system and so on.Therefore,it is of great significance to carry out the research on the airborne radar forward superresolution method and design and complete the corresponding radar simulation software system for the subsequent airborne radar forward simulation,verification analysis and improvement of imaging performance.Based on the theory of airborne radar forward super-resolution imaging,several common and improved forward super-resolution imaging methods are studied in this thesis,and a simulation software system for airborne radar forward resolution imaging is designed and implemented.The specific work is as follows:(1)Based on the geometric model of airborne radar forward view imaging,azimuth convolution model is established,which lays a theoretical foundation for subsequent super-resolution imaging method.(2)Several classical airborne radar forward-looking super-resolution imaging methods are studied,and on this basis,an improved iterative adaptive forward-looking super-resolution imaging method is studied,which significantly reduces the computational complexity.(3)The overall simulation software architecture of the airborne radar forward looking super-resolution imaging system is designed,and based on the engineering application of the airborne radar forward looking imaging system,combined with VS,qt,MySQL and other software,it is divided into information communication,interactive control,data storage,Modules such as data processing,result display,logging and data simulation are designed and implemented.(4)The simulation software defines the function,combines and migrates Matlab part of the function,and uses multi-thread,DLL and so on to shorten the data processing time,so that the simulation software can complete the real-time display and simulation verification in a shorter time.It is verified that the improved airborne forward superresolution method can reduce the computation cost,and the simulation software can complete echo generation,pulse compression,walking correction and azimuth processing.
