摘要/Abstract

摘要： 在机载导弹逼近告警中，识别远距红外点目标是一个非常重要的任务。通过分析比例导引规律和红外目标成像原理，完成了三维空间中的地面干扰源和按比例导引法制导的导弹到红外探测器二维空间的像点映射，进而对这两种点目标的成像进行对比仿真，发现它们的运动特性明显不同。分析结果表明，可根据点目标成像点运动特性的不同，对导弹和干扰源进行区分。

Abstract: The recognition of far infrared spot target is a very important assignment in AMAWS（Airborne Missile Approach Warning System）. By analysis of proportional guidance and infrared imaging theory, the mapping is solved, which from missile（of proportional guided） and disturber（on earth） in real three-dimensional field to pixels on two-dimensional infrared focal plane array. By simulating the imaging of the two spot targets, the movement feature is discovered distinctly and contrastively. The analysis result show the missile and disturber can be differentiated by the differences of the imaging movement feature.

Key words: missile approach warning, proportional guidance, infrared spot target, movement feature
