Coherent Detection Technology Based on Electro-optic Effect for Inter-satellite Tracking
基于电光效应的相干检测星间跟踪技术

A novel inter-satellite tracking system with high sensitivity and precision has been developed. The key feature of the system is the incident beam conical scan caused by LiNbO 3 crystals with linear electro-optic effect. The incident beam direction can be estimated by coherent detection. These estimates are fed back to control fine pointing mirror for inter-satellite tracking.
