分布式雷达系统误差修正

A Registration Algorithm for Distributed Radars System

系统误差修正是多雷达和分布式雷达跟踪系统中的基本问题。分布式雷达的系统误差修正与传统的多雷达系统误差修正方法有较大的差异,传统的多雷达系统误差修正常采用线性最小二乘的方法,而分布式雷达需要采用高斯牛顿迭代方法。因此有必要对分布式雷达系统误差修正问题进行研究,为工程应用提供参考。文中给出了一发三收分布式雷达系统误差修正的方法,并进行了仿真,得出了相应的结论。

Sensors registration is a basic problem in mutiradars and distributed radars tracking systems. The registration algorithms are big different between distributed radars and mutiradars systems. Traditionally, it is usually solved by the linear least squares methods for mutiradars system. But the gauss-newton iterated algorithm is needed for distributed radars system. So it is necessary to investigate the registration algorithm for distributed radars system. The registration method is obtained for one-transmitted and three-received distributed radars system. At last simulation results are given.
