Study of Convolution Jamming Technology Based on DRFM

Aiming at the fact that the false target density is difficult to be improved when using the conventional jamming means to jam linear frequency modulation radar signal with wide pulse width,this paper presents a new jamming mode generation technique,which stores the received radar signal sample into digital radio frequency memory(DRFM),then reads the sample in DRFM with time delay,generates and transmits the radio frequency(RF) jamming signals through the innovative calculation.This paper analyzes and designs the technique from aspects of principle and engineering,and performs half-practicality simulation,the result validates the validity of the jamming generation technique.
