Research on position error of external radiation radar sensor based on 3d positioning algorithm

Abstract

The paper establishes a measurement-launch station correlation model of a single-frequency off-line radar system, derives the principles of the three-dimensional TOA positioning method and the two-dimensional TOA positioning method to estimate the target height, and gives the analysis of the GDOP positioning accuracy of the corresponding algorithm, and Through the simulation verification of a three-transmission single-receiving external radiation source positioning model, the effects of different algorithms on positioning accuracy and measurement-transmission station correlation are analysed. The results show that using the two-dimensional TOA positioning method to estimate the target height can improve the measurement-transmitting station correlation probability of the single-frequency off-line radiation source radar.
