有源无源雷达信息融合系统误差估计

System Error Estimation for Information Fusion of Active Radar and Passive Radar

有源雷达和无源雷达系统误差估计是实现有源无源雷达信息高精度融合的关键环节之一。由于时差定位无源雷达具有与有源雷达不同的误差分布特点,多有源雷达之间的系统误差估计方法已不适用于无源雷达与有源雷达之间的系统误差估计。文中提出一种系统误差估计方法,利用有源雷达和无源雷达对同一目标的观测,同时估计有源雷达的系统误差和无源雷达的时差系统误差,并通过仿真实验验证了该方法的有效性。

System error estimation for active radar and passive radar is the key for realizing high precision Information fusion of passive radar and active radar. Passive radar has different error distribution characteristics because of different location methods from active radar, and the existing methods of system error estimation for active radar network arent applicable to the radar network of active radar and passive radar. This article proposes a method for system error estimation based on observation data on the same target by passive radar and active radar. The simulation results show that the method works effectively.
