摘要

针对弹载相控阵惯性视线重构问题,提出了基于相对运动状态估计的视线角/角速率重构方法,与传统方法相比,文中提出的方法在稳定坐标系下建立导弹-目标运动状态动力学模型和雷达导引头观测模型,无需对导引头测量的角信息使用微分网络,避免了测量噪声的放大。在分析系统可观测性的基础上,采用UKF滤波算法进行状态估计,根据估计值重构视线角速率。仿真结果表明,该方法对机动目标的重构角误差<0.5°,角速率误差<3°/s。

Abstract

A new approach for inertial line-of-sight (LOS) reconstruction in phased-array seeker was proposed based on the estimation in missile-target relative state. Compared with traditional approach, the new approach avoids differential implement which would induce noise amplification. In this paper, the modeling of missile-target relative motion and a phased-array seeker measurement in inertial Cartesian frame were described, the observability of overall system was analyzed, too. Unscented Kalman filter was designed to estimate relative state and reconstruction LOS angle and rate. Expected performance was illustrated through the simulation results, indicating that LOS angle error < 0.5 deg, LOS rate error <3 deg/sec.

Key words： phased-array radar seeker; UKF filter; LOS rate estimation; observability analysis
