| The multi-functional two-dimensional perimeter radar system integrates a variety of working modes,has the ability to monitor the targets of people and vehicles on the ground and UAVs at low altitude at the same time,so it has strong practicability.Compared with the traditional mechanical scanning radar system,this radar system abandons the mechanical structure of radar array and turntable,and uses two-dimensional electronic scanning technology for beam control,which makes the radar pointing more accurate,the angle transformation more rapid,so it has better detection performance.With the rapid development of modern science and technology,this perimeter radar system with strong detection performance,high precision and multiple functions has attracted extensive attention at home and abroad and has great development potential.The research content of this thesis is a multi-functional two-dimensional perimeter radar signal processing system.Firstly,this thesis introduces the research background of multi-functional two-dimensional perimeter radar and the related theories and algorithms of radar signal processing;Secondly,according to the system index requirements,the overall radar scheme and signal processing system scheme are designed,including two-dimensional beam scheduling scheme,algorithm flow,parameter design and hardware selection;Thirdly,the radar signal processing system based on FPGA chip is designed and implemented,including signal processing algorithm module and interface module,and the functions of these modules are simulated and verified;Finally,the hardware debugging and functional performance verification of the whole system are completed in the hardware debugging platform and the whole radar system,and the test results are compared and analyzed.After debugging and verification,the multi-functional two-dimensional perimeter radar hardware system operates normally,the radar algorithm scheme is feasible,and all functions and performance indexes meet the requirements. |
