有限声速的纯方位算法
Bearing-Only Arithmetic with Finite Sound Velocity
摘要
Abstract
Aiming at the arithmetic of observing target which has uniform course and velocity, using target motion factor and average sound velocity to be the parameters for estimated, the analytic formulas to compute gradient vector and Hessian matrix for the nonlinear least square objective function are given. Based on these formulas, it can construct the arithmetic and program realization for estimating target motion factor. Some numerical experiments indicate that the trust region arithmetic and Levenberg-Marquardt arithmetic have almost the same computational accuracy to lsqnonlin which is a Matlab function used specially for solving nonlinear least square problem.关键词
