网络化多平台协同探测系统空间算法研究

摘要

研究网络化多平台协同探测空间一致性算法问题.未来海战场协同反导作战过程中,由于平台自身的姿态偏差和传感器探测的系统偏差,使得协同探测的效果并不理想.针对不同探测平台(机动平台)传感器对目标探测的量测关系,在将局部笛卡尔坐标转换到以传感器为原点的地理坐标系的基础上,给出了一种广义最小二乘法的机动平台空间多平台探测空间对准算法.最后,利用Monte-Carlo仿真对算法验证了算法的科学性,有效地对传感器的系统偏差和平台导航系统偏差进行了估计和修正,为探测系统空间一致性研究提供了理论参考.%Study cooperative detection space consistency algorithm of network multi platform. Owing to the attitude deviation of the platform and the inherent errors of the sensor system, the performance of the cooperative detection is not so satisfied. This paper presented an registration algorithm for the maneuvering platform based on generalized least squares ( GLS) by using the measurement relation of the sensors on different detection platform ( maneuvering platform) and the target detection on the basis of transforming local Cartesian coordinates to the geographic coordinate system. In the end, the effectiveness and the performance of this algorithm were approved to be effectual by Monte-Carlo simulations. The estimation and correction for the sensor system deviation and platform navigation system error were gived, which provides a theoretical reference for the detection of the consistency of system space.
