Abstract:

The existing systematic bias registration algorithms require that systematic bias models should be known before estimation; therefore subsequent target state estimate is susceptible to the estimation results of systematic biases. To cope with the above deficiencies, the problem of how to effectively track targets in the presence of systematic biases is studied in this paper for the airborne and shore-based radar collaborative defense system. An effective robust target tracking algorithm in a ground-air collaborative defense system is proposed. The simulation result shows that the algorithm proposed in this paper can obtain unbiased, stabilized and effective estimate of the target state. And it is robust to changes in systematic biases, adaptive to abnormal situations that may arise in practical application, and can provide effective target information for follow-up decision making.

Key words: systematic bias, sensor registration, collaborative defense, robust tracking, target state estimate, radar
