Design And Implementation Of Radar Active Jamming General Platform

With the development of electronic warfare technology,electronic warfare plays an increasingly prominent role in modern warfare.Radar is the eye of battlefield,and the countermeasure against radar has become an important part of electronic warfare.Radar countermeasure takes radar and its components as combat targets.It is an effective combat behavior to suppress the use of enemy electromagnetic spectrum.With the continuous development of radar jamming and anti-jamming technology,some new systems of radar and new anti-jamming measures have emerged,which make the battlefield electromagnetic environment more and more complex and pose new challenges to the development of radar active jamming technology.This paper mainly focuses on the design and implementation of radar active jamming general platform,and research work is made on the following aspects:First,the ralated technologies of radar avtive jamming technology are discussed.Mainly includes digital orthogonal up-down converter technology,radar signal sampling method and several typical radar active jamming modes,including multiple false targets deception jamming,range-velocity simultaneous pull-off,ISAR imaging jamming,dense active multi-false-target jamming and smart noise interference.The related technologies are simulated and validated in this paper,which lays a foundation for the development of hardware platform and the realization of technology.Second,aiming at the design of general platform for radar active jamming,the requirements are analyzed.And the main components are selected,including the selection of ADC chip,DAC chip and FPGA chip.Then the power circuit and clock circuit design were analyzed.On this basis,the schematic design of the general platform is completed,the design of PCB and the production of hardware board are carried out.Third,based on the hardware platform,the hardware test program and interference implementation program are written in Verilog HDL language,and the hardware performance test and jamming mode function test are carried out.In the part of hardware testing,the key technical indexes of ADC and DAC are tested and verified.In the function test part of jamming mode,the typical radar active jamming mode is tested,and the indexes are tested by related instruments,which verifies the correctness of the system design.
