摘 要:随着科学技术的不断进步,军事目标也向着小型化、超高速、低可探测度的趋势发展,因而对目标的探测与识别能力也提出了更高的要求。文中在深入分析点目标成像过程及其能量分布的基础上,提出基于偏态瑞利分布点目标能量计算方法,并通过红外辐射特性测量精度对比实验进行验证,得出应用该方法的辐射强度测量偏差可控制在8%以下,而且测量离散程度更小,可有效区分弥散点目标和背景灰度值,证明该方法具有良好的工程适用性,较高的测量精度且广泛的应用前景。With the continuous progress of science and technology, military targets are developing towards miniaturization, ultra-high speed and low detectivity, so the detection and identification ability of targets is also put forward higher requirements. Based on the deep analysis of point target imaging process and on the basis of energy distribution, based on abnormal Rayleigh distribution of point target energy calculation method, the infrared radiation characteristics and has a better precision than the experimental verification, it is concluded that the measurement deviation of radiation intensity can be controlled under 8%, and measuring the degree of discrete numerical smaller, can effectively distinguish between the point target and background. It is proved that the calculation method has good engineering applicability, high measurement accuracy and wide application prospect.
