Abstract:

In modern electronic warfare,radar jammers use deceptive jamming methods for the new radars.Based on the mechanism of DRFM,a detailed introduction is given to the dense false target mechanism of controlled variable interval.False targets are produced based on FPGA IP core internal FIFO,by controlling the depth of FIFO storage to generate the distance deception of false target signal and the transmission number by switch control false target.The validity of the false target mechanism is demonstrated by simulation analysis,and feasibility of the dense false target hardware is verified.A false target to realize hardware am/fm method is also given to provide reference for related radar jammer hardware implementation.
