摘要:

针对小型智能飞行器(miniature intelligent air-vehicle, MIA)低精度微惯导系统的动态初始对准和校准问题, 提出了基于雷达的导航信息传递技术。将雷达及其载体当作一个刚体, 设计了基于雷达的导航信息传递系统; 基于雷达被动测向原理, 提出了测定雷达主瓣波达方向(direction of arrival, DOA)的多重镜像压缩的传播算子(multiple image compression-propagator method, MIC-PM)估计算法。理论与仿真分析表明, 相对于PM算法, MIC-PM算法计算量明显减少, DOA估计时间可达到9.3×10-3s, 满足MIA导航信息传递的实时性要求; 同时, 在低信噪比情况下的估计精度有所提高。

Abstract:

Aiming at the problem of dynamic initial alignment and calibration for the low precision micro-inertial navigation system of the miniature intelligent air-vehicle (MIA), the navigation information transfer technology based on radar is proposed. The radar and its carrier are regarded as a rigid body and the navigation information transfer system based on radar is designed. Based on the principle of radar passive direction finding, a estimating algorithm which calculates the direction of arrival (DOA) of the radar main lobe is established, which is called as multiple image compression-propagator method (MIC-PM) algorithm. Theory and simulation analysis show that the MIC-PM algorithm can greatly reduce the computation relative to PM algorithm, and the DOA estimating time is 9.3×10-3s, which satisfies the real-time requirement of the MIA navigation information transfer. At the same time, estimation precision is improved in the case of low signal to noise ratio.

Key words: miniature intelligent air-vehicle (MIA), navigation information transfer, radar passive direction finding, multiple image compression-propagator method (MIC-PM) algorithm
