Considering that the detection probability of false target is high under range-velocity deception jamming,which is similar to angle-measurements to the target,we proposed a low observable target tracking method based on radar network.At first,the angle-measurement set of each radar is partitioned according to the angle information,and the measurements within the same partition are fused.Then the hypothesis testing for the same source measurements of each partition is realized and the missed target measurements are compensated.Simulation results verify the feasibility and validity of the proposed algorithm.
