| 摘 要： | 众所周知,纯方位伪线性估计有着严重的偏差问题。以伪线性估计的理论模型为基础,研究它在纯方位问题中的应用。将伪线性估计的偏差分离出来,形成偏差补偿估计,对这种估计方法进行仿真计算,并与伪线性估计相比较,经蒙特卡罗仿真研究,其估计偏差确实比伪线性估计小,算法性能反映在一些典型态势上。

| Abstract: | The bearings-only pseudolinear estimator is known to suffer from severe bias problems.Based on the theoretical mathematical procedure of pseudolinear estimator,this paper will investigate the application in bearings-only problems.Estimation bias will be separated from pseudolinear estimator,and form bias compensation estimator.It implements this approach,and compares with pseudolinear estimator.In Monte Carlo simulation,the bias of bias compensation estimator is smaller than pseudolinear estimator,The algor... |
