仅有角度信息的红外多传感器异步目标跟踪

Angle-only Asynchronous Target Tracking with Infrared Stations

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。

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 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.
