A novel radar radiation control strategy based on passive tracking in multiple aircraft platforms

This paper proposes a radar radiation control method based on cooperation tracking of multiple sensors. The main idea of the method is passive tracking in multiple platforms is used preferentially, while radar tracks target timely according to the tracking accuracy. In this paper, a tracking accuracy metric called interactive multiple model predicted covariance (IMMPC) is derived by IMM-EKF algorithm. By comparing with the pre-defined threshold, whether or not the radar transmitter radiates energy is determined. Simulation results show that the proposed radiation control method can reduce the radar radiation times effectively and have a good performance of low probability of interception (LPI).
