Using the laser transmission characteristic in atmosphere channel and request for APT, a new type of APT system is designed for real time communication. Work principles of each part are discussed in details. On the basis of a new idea of target locating and tracking algorithm, specifically flow and corresponding tracking algorithms is designed in order to(More)
According to the characteristics of laser communication at sea, we propose a sort of step scanning acquisition method for maritime communication. Comparing with traditional continuous scanning method, it can get velocity, high sensitivity and large acquisition range. The proposed acquisition method is based on Yang's noisy model. Through quadrant devices,(More)
