Research of pulsed-doppler radar jamming system based on DDS

An new jamming system which used to pulsed-doppler radar was introduced in this paper. Firstly, the configuration and its characteristic of jamming system based on digital frequency synthesizer was analyzed and simulated. Then, the collimated precision and equation of extent and phases of pulsed-doppler radar was analyzed, on the condition of jamming affected. This technology and corresponding arithmetic was simulated in computed. The simulation results show that the jamming effect of jamming system based on digital frequency synthesizer was comparatively well, and can diffusely applied to pulsed-doppler radar.
