Abstract: For the problem of existed main lobe track deception jamming technology only consider the limits of motion parameters and task of signal jammer, by means of referring to the general track association rule, the enactment method of phantom track is put forward, and the motion parameters and interference signal modulation parameters of the jammer is deducted. Based on the work mode of the signal jammer, the feasibility of multi machines cooperation combat the netted radar is explored. The simulation results show that interference signal can be identified by enemy radar, and it can achieve the anticipate result under the situation about two jammers combat two radars, which lays the foundation for the netted radar confrontation under the complex situations.
