摘要
在前人工作的基础上,分析了干涉探测的基本工作原理;采用波动光学理论、平面波近似和非相干叠加等方法对干涉探测技术进行了理论分析和数学建模,并通过计算机仿真验证了该技术的可行性。通过与传统光电探测技术的比较发现,干涉探测技术更适用于在强天光背景下对暗弱目标的搜索。
Abstract
On the basis of prior works, the basic principles of interferometric detection are analyzed. The theoretical analysis and mathematical modeling of interferometric detection technique are performed by means of the wave optics theory, plane wave approximation, incoherent superimposition, etc., and the computer simulation is used to confirm the feasibility of this technique. By comparison with the traditional photoelectric detection technique, it is found that the interferometric technique is more suitable to the search of dark and weak objects in the context of strong sky background.
