Abstract:

Aiming at the existing target height estimation algorithms’ deficiencies that the lack of consideration for the information processing flow in the real multi-radar network would make the algorithms hard to be applied in the practical system, the problem that how to effectively compensate for target height in the presence of the incomplete measurement is studied from the two aspects of information processing flow and the information processing approach under the shore, sea and air collaborative defense system. The simulation result shows that the proposed algorithm can obtain the unbiased, stabilize and accurate estimate of the target state which can meet the need of target attribute identification and threat evaluation. At the same time, the simulation verifies that the algorithm is highly adaptable to the target cruising altitude and can solve the height compensation problem of the target which flies in the same observation of shore, sea and air detect units at any altitude.
