摘要
对光学测量数据中是否存在系统误差以及存在何种系统误差进行诊断是测量数据建模与处理首要任务。本文利用靶场光测数据的冗余性，建立了基于残差准则的系统误差诊断模型。首先以最简单的常值误差对弹道分量影响规律的复杂性为例，说明识别数据中系统误差的重要性。接着根据光学测角模型，建立了带有系统误差的测量数据残差模型，设计了系统误差检验模型的统计量。从工程实践应用来看，本文方法可以有效地识别数据中的系统误差，对改进传统数据处理方法、提高数据处理能力具有一定的参考价值。
To diagnose the existence of systematic errors in optical measurement data and the existence of any systematic errors is the primary task of measuring data modeling and processing. In this paper, the system error diagnosis model based on residual criterion is established by using the redundancy of the range measurement data. Taking the complexity of the simplest constant error for the ballistic component as an example,it shows importance of identifying systematic errors in data. According to the optical angle measurement model, the residual model of measurement data with systematic error is established, and the statistics of the system error test model are designed. From the perspective of engineering practice, this method can effectively identify the system error in the data, to improve the traditional data processing methods, improve data processing capabilities have a certain reference value.
