Abstract :
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, we processed the acquisition signal and set up QD model. From the simulation result of RBF neural network, we find only few errors exist.
