AN ALGORITHM STUDY OF FUSION LOCATION FOR THE RADAR NETWORKING SYSTEM BASED ON QUASI-NEWTON ALGORITHM

摘要

For the fusion location problem of the noised detection plots of multiple networked radars (NRs), the proposed fusion location algorithm based on the quasi-Newton algorithm, takes advantage of solution theory of the nonlinear equations by DFP quasi-Newton algorithm, considers error characteristic of multi-radar, from the point of view of optimization, settles the problem of the quick approximation computation of true position of the airspace target in numeric calculation manner. The simulations demonstrate that the positioning accuracy of the proposed algorithm is better than the conventional algorithm of the bearing accuracy weighted (BAW) and the weighted least squares (WLS) algorithm. Even if compared to the minimized one of the detection errors of NRs, this proposed algorithm, is obviously predominant.
