Ballistics Data Post-processing Analysis And Research

The new-type radar theodolite with multi-sensor observes the flying target, which changes its flying track along with time. This work mode is called outer track synchronized measure. This paper explains how to process the original data from radar theodolite efficiently, thus the accurate movement parameters, shot-target relative movement parameters and shot-target meeting parameters can be acquired.This paper's mainly researches in the following ways. First is about angle synthesis and data error correction, which includes the correction of device system error, atmosphere refraction error, tracking error, interpretation location error and time delay error; Second is about measure and control coordinates, including converting methods from radar theodolite coordinates, missile launch coordinates, the earth's core space angle coordinates and measure station normal coordinates to normal launch coordinates; Third is about data processing models, including two or more theodolite angles (IR, TV) rendervous orientation, radar theodolite distance measurement, angle measurement solo orientation and three-radar distance orientation.In the end, this paper analyzes the data results processed by three different post-task data processing methods under the same measure condition. Thus it presents the data basis both in quality and quantity for the station position selection, original data selection, high precision region confirmation and error correction of the measure station. The basis makes radar theodolite work better in the engineering application to achieve higher battle effectiveness.
