Its accuracy and stability are very important for applications such as positioning, navigation, guidance and so on. However, due to the incomplete randomness and bias of the measurement, the accuracy and stability of the target coordinate measuring instrument are limited. Therefore, this paper studies the parameter design and estimation method of the target coordinate measuring instrument under incomplete random and biased measurement.Firstly, the concept and related theory of incomplete random and biased measurement are introduced, and the impact of this problem on the target coordinate measuring instrument is analyzed. Then, based on the working principle and model of the target coordinate measuring instrument, a parameter estimation method based on weighted least squares 精品文档---下载后可任意编辑method is proposed, and the specific implementation process of the method is elaborated in detail. Finally, in order to verify the effectiveness of the proposed parameter estimation method, experiments are conducted, and the feasibility and practicality of the proposed method are further verified by analyzing experimental data.The research results of this paper have certain theoretical and practical significance for improving the accuracy and stability of the target coordinate measuring instrument.Keywords: incomplete randomness; biased measurement; target coordinate measuring instrument; parameter design and estimation.
