Abstract: A method of radar jamming based on a frequency diverse array jammer is provided. In the method, jamming signals are transmitted through a frequency diverse array, so that the jamming signals transmitted by each array element are different in frequency. On one hand, the power of the jamming signals is enhanced by adopting an array form, which causes serious trouble to the target detection of enemy radar in the frequency domain. The frequency diverse array jammer uses a digital radio frequency memory as a front end basic component, stores and processes the received enemy detection signal, flexibly uses repeater jamming or smart jamming, and finally transmits the jamming signal in a frequency diverse array antenna mode to generate more false targets than conventional jamming, thereby effectively destroying the detection and tracking of the enemy radar on our side moving targets.
