相控误差对光束相干合成的影响
EFFECTS OF PHASING ERRORS ON BEAMS COMBINATION
-
摘要: 本文在真空合成孔径系统光束控制工作的基础上,进一步分析和讨论了光束相位控制误差(调相的倾斜、活塞误差及调焦误差)对光束相干合成的影响,给出了相应的物理模型,并进行了数值模拟计算和三维图形演示。Abstract: Based on the research beam control for synthetic aperture systems in free space, this paper analyzes and discusses effects of phasing errors on beams combination. The phasing errors include piston errors, tilt errors and focus errors. The corresponding physical models are developed.Finally results of numerical computations are given.
