一、引言许多红外目标与景物模拟曾采用与背景差不多具有同样温度的可分辨图型,或在更高温度下的不可分辨的(点)源。在试验中,这两种方法都曾使用过。第一种方法是利用有关研究景物的某些可取得的数字化数据作为对数据处理系统的输入,以试验其识别能力。使用第二种方法时,是在某种典型条件下测试整机跟踪器,以评定其性能。很容易找到典型条 I. INTRODUCTION Many infrared targets and scene simulations have used a distinguishable pattern that has almost the same temperature as the background, or an indistinguishable (point) source at higher temperatures. In the experiment, both methods have been used. The first is to use some of the available digital data about the landscape as input to a data processing system to test its ability to recognize. The second method is to test the whole tracker under some typical conditions to evaluate its performance. It is easy to find the typical bar
