Research On The Fast Implementation Method Of Echo Simulation Of Guidance Radar

Guidance radar is one of the important types of radar in modern radar system.The main task of guidance radar is of incoming enemy target detection,investigation and identification and tracking,at the same time to our interceptor missiles and to implement the whole process control,until the destruction of the enemy attacking targets.In the development and testing of the guidance radar,a large number of field tests are usually required,Including radar system debugging,performance testing,confrontation experiment,radar effect evaluation,etc.Such a large number of tests if there exists a simulator can real-time accurately reproduced the echo which contains radar target and its environmental information,can greatly shorten the development cycle and reduce development cost.The radar simulator is born to meet this demand.Guidance radar echo signal simulation is based on DRFM(digital radio frequency memory)system with high-speed signal transmission technology,through RF cable or the communication equipment receiver and transmit radar signals and the high performance of FPGA and DSP processor combination structure,realizes the simulation of echo signal.The radar echo simulation fast implementation method of research,proposed and designed the new can achieve fast echo simulation of modulated structure,ISE software simulation and online ChipScope debugging,and ultimately achieve the based on FPGA + DSP real-time radar echo simulation.First of all,introduced the guidance radar echo simulator research status and development trend.At home and abroad to radar echo simulator research status were compared,summed up the domestic radar echo simulator of the strengths and shortcomings,and further introduced the development trend of radar echo simulator.Therefore,we propose a fast implementation of the method in this paper,a new radar echo simulation.Secondly,the basic principle of radar echo simulation,modulation structures are introduced,the modeling of radar target echo,for the design and Realization of the system,the third chapter provides theoretical basis and reference.Third,detailed introduces the system design and implementation of fast simulation of radar echo,including the hardware,function and index as well as the software design and implementation.Fourth,the design and implementation of radar echo simulation system functions and performance test system.Finally,make a summary of the work of this paper,and pointed out some improvement and with the development of science and technology can better solve the problem.
