Radar networking via various technical measures to improve the ability of the radar system of four anti-jam. Repressive noise because the need to launch multi -orient and large scope interference, power limits become a problem. In this paper on the basis of the characteristics of radar networking and interference power problem presents a measure contain distributed repressive interference and False track interference. Compared with the traditional high-power way of interference, distributed interference has big range interference section, close advantage and can change the shape of the exposure when changing the jammers distribution. Adaptive wave form technology can realize the jamming signal of time and space launch asynchronous, making that the jammer can simultaneously implementation to different radars of radar net false track deceptive jamming be possible. Through the simulation analysis, the composite interference of the distributed repressive interference and false track interference for netted radar can effectively reduce the oppressive interference power, and form an effective interference.
