摘要： 提出一种估计连续波雷达常值系统误差和轨道参数的非线性方法。该方法把一段较长时间的数据集中处理，运用样条函数描述轨道参数，建立精确的少参数的非线性模型，据此估计系统误差和轨道参数。和传统的最佳弹道估计（ＥＭＢＥＴ）方法比，该方法待估参数少、模型误差小、精度高。

Abstract: n this paper,the author presents a nonlinear estimation method of theconstant systematic errors and orbit parameters of continuous wave radar systems.This method processes data in a long time interval altogether,using splines to describeorbit parameters,thus establishing a high precision nonlinear model with fewerparameters.The systematic errors and orbit parameters are thus estimated byapplying this model.Compared with the traditional EMBET method,this method hasthe advantages of much fewer parameters,small model errors, and high accuracy.
