Research on TDOA/SDOA Joint Estimation Algorithm in Wideband Passive Location
摘要
Abstract
To solve the contradiction between computation complexity and estimation accuracy in wideband passive location systems,an algorithm based on frequency scaled correlation and nonlinear least square is proposed.In this method,the initial value of TDOA/SDOA can be obtained at low computation cost,as the frequency correlation improved by frequency resampling is adopted.Then the average square difference function is used to replace the wideband cross ambiguity function to get the accurate value of TDOA/SDOA through nonlinear least square. The high estimation precision and low computation complexity of the algorithm are validated by simulation results.关键词
