Abstract

Abstract: The optimum scheduling for radar radiation occasions with emission time constraint is concerned, the model of the radar radiation occasions optimum scheduling is established with optimizing objective function the trace of target statement estimation error covariance, the rule of optimum scheduling for radar radiation is drawn. Research results demonstrate, given the emission time constraint, the closer the radar radiation occasions to the end of the time segment is, the less the target statement estimation error is. A method of real-time radar radiation controlling is put forward based on the rule, using the prediction covariance threshold and the estimation covariance threshold to control the radar radiation on real time. The simulation results show that, the proposed method can control radar’s radiation to track targets smoothly, the radar radiation times is related to the prediction covariance threshold and the estimation covariance threshold, and radar radiation can be controlled by setting different parameter based on different tracking demand. These conclusions can be used for optimum scheduling for radar radiation to obtain high estimation accuracy.
