Cooperative Jamming of Multi UAVs to Netted Radar

Abstract

This paper analyzes the cooperative jamming problem of multi UAVs to netted radar, controls the given constraints, adopts the optimal control algorithm to analyze the movement law of UAVs in layers. Based on the single UAV track model, the cooperative jamming track model of multiple UAVs is established, and the optimal UAV track number and the number of false target tracks are calculated, The movement law of UAV track and false target track is analyzed. Firstly, according to the range deception principle of cooperative jamming of UAV to netted radar, the kinematics model of single UAV is established, and the motion parameters of false target point and UAV are obtained; on the basis of single UAV, the motion model of multiple UAVs Cooperative jamming netted radar is established, and the motion parameters of false target point and UAV are also determined. Since multiple UAVs need to meet the “homology test” of Netted Radars, it is necessary to select the optimal control algorithm to optimize the control of multiple UAVs to obtain the optimized UAV and false target track, so as to achieve the purpose of cooperative jamming. Then, according to the optimal trajectory of UAV, the change of speed is determined, and the number of UAVs is determined by selecting the number of time points of UAV moving in a straight line with uniform speed by optimizing the value of speed. In this paper, by layering the tracks of potential false targets, several reasonable tracks which are most likely to exist are selected, and then the tracks and motion laws of the other two UAVs are determined by the linear equation between these track points and the other two radars which determine the track points, flight altitude and flight speed.
