Radar network and ECCM of radar network is introduced.Using Extended Kalman Filter(EKF) applied on the system equation for model of spatial uniform velocity rectilinear movement horizontally regular circumferential movement and the measurement equation for radar network of different jamming level,target tracking of radar network will be realized in the presence of jamming.By the simulation of target tracking and comparison of their tracking error for the jammed radar network and no jammed radar network,the conclusion is obtained that jamming effect of ECM for radar network is very limited by using oppressive jamming and range-deceptive jamming.Therefore,the effective countermeasure of radar network needs cooperative jamming of integrated multimode such as angle-deceptive jamming.
