| 摘 要： | 对复杂背景下传统作用距离方程无法准确评估红外探测系统作用距离的问题，提出了玫瑰扫描体制下复杂背景中不同辐射亮度区域被探测的概率计算方法，结合推导的玫瑰扫描红外探测系统作用距离模型，得出复杂背景下玫瑰扫描红外探测系统作用距离概率模型。基于红外热像仪采集的背景灰度计算玫瑰扫描红外探测系统响应脉冲幅值的计算方法，利用外场实测数据对该模型进行验证，并与实验结果进行了对比分析，结果证明改进后的概率模型能够一定程度解决复杂背景玫瑰扫描红外探测系统作用距离估算的问题，具有一定的实用价值。

| Abstract: | Operating distance of Rosette scan infrared detection system is hard to be estimated by infrared detector operating distance formula in complex background. So correlated to the operating distance model of Rosette scan infrared detection system, the model working in complex background was developed. Using the algorithms that calculates the Rosette scan infrared detection system responses pluses characteristics via gray scale of background collected by infrared thermal imager and verified by field tests, the result shows that the improved model can estimate the operating distance of Rosette scan infrared detection system under complex background more efficiently. |
