Simulation Analysis of Multi-sensor Track Fusion Based on Bearing-only Information

Multi-sensor information fusion is more and more important for modern battlefield environment.However,owing to the performance difference among different sensors,it is different on track association correct rate by using different track association methods,the correct rate of track association is essential to track fusion,so it is worth exploring deeply.This paper first theoretically analyzes the main influence factors and their influence degree to the track fusion performance of heterogeneous sensors,and then brings forward the track association method of heterogeneous sensors.Simulation results show that the track fusion effect can be enhanced by improving the measurement precision of sensors,decreasing the difference of measurement precision among heterogeneous sensors and enhancing the track association correct rate of heterogeneous sensors.
