仅有角度信息的红外多传感器异步目标跟踪

跟踪机动目标,红外单站有不少缺陷,多站可以提供比单站多的信息。然而,多站存在同步的问题。通过对状态更新过程的分析,发现跟踪可以异步实现。多站采用异步的处理方式极大的灵活了数据的处理,而且可以通过多站组网扩大跟踪范围。为解决系统方程的非线性,采用伪线性观测方程。仿真结果表明本方法可以实现对空中目标的稳定跟踪,且观测站增加可以提高精度。

Angle-only Asynchronous Target Tracking with Infrared Stations

Tracking maneuvering target with single station has many limitations,but multi-station can offer more information.Then multi-station has a problem of synchronization.By analyzing the course of updating the state,it's found that the tracking can be realized asynchronously and the multi-station dealing with the data in this manner makes the work completely flexible.So,multi-station in a net can increase the tracking range.To solve the non-linearity of the systems,a pseudo-linear observational equation is adopted.The simulation results indicate that this method is stable in tracking aerospace target.Furthermore,the increase in the number of the observation station can improve the precision.
