摘    要:针对红外单站被动定位技术中空中机动目标的运动速度不断变化这一实际情况,提出了一种基于红外相机运动特性的对目标的运动速度进行实时更新的校正算法.该算法克服了大多基于匀速直线运动这一空间模型的红外单站被动定位方案目标速度不变的缺点,客观地反映了空中机动目标的实际运动状况,不仅能对目标的运动速度进行实时准确的更新校正,而且可推演出一种新的红外单站被动定位算法,对推动红外单站被动定位技术的工程实用化进程具有重要的意义.

关 键 词:红外单站  被动定位  相机运动  速度实时更新

Abstract:In face of the fact that the movement velocity of an aerial mobile target in the infrared mono-station passive location technology is always in changeable, a real time velocity updating algorithm for aerial mobile target based on infrared camera motorial speciality is presented. The algorithm can effectively overcome the shortcomings of velocity invariability of most infrared mono-station passive location scheme based on constant velocity linear movement model and objectively describe the actual moving status of aerial mobile target. It not only can make accurate correction to the velocity of aerial mobile target but also can deduce a new algorithm of infrared mono-station passive location and have important significance in the engineering utilization process of infrared mono-station passive location technology.
Keywords:Infrared mono-station  Passive location  Camera movement  Real time velocity updating
