动态最小二乘法及其在动态观测系统中的应用

APPLICATION OF DYNAMIC LEAST SQUARES TO DYNAMIC MONITORING SYSTEM

The conventional least squares is an effective method for processing the observed data, which has been applied in many fields.However, it is based on static point of view, i.e. all the observed data are regarded as data measured at the same time and the same static state. In modern earth crust movement, including surface movement caused by mine exploitation, the objects to be measured are dynamic, and the data to be measured change with time,and the effect of environmental state on the observed data also change with time. It is obvious, if the classic least squares method, which does not take into consideration of time and state factors, is used to deal with the observations, some distortions would appear in the results. For this we have studied and proposed a Dynamic Least Squares method, which takes into consideration the above-mentioned parameters, and is used to optimize design and to process data measured by dynamic measuring system.
