摘要
Abstract
A location algorithm for near space radar networks based on angle information is researched in this paper, firstly, the relationship equations of target and radar stations are translated into linear equations based on geometric relationship, and the least-square solution including noise is found. And then the location issue is transformed into unconstrained extremum problem by the way of maximum likelihood estimation, taking the least-square solution as an initial value, the more accurate positioning solution is worked out using DFP algorithm, and the detailed process is given at the same time. Finally, the expression of geometric dilution precision (GDOP) is deduced, and simulation analysis for the performance of the algorithm and the location accuracy is presented, all of this proves that the algorithm is effective.关键词
