Design and experimental study of fast acquisition system for optoelectronic target

In the free-space optical communication system, the acquisition technology of opto-electronic target for terminal platform is a key technology to establish a communication link. However, conventional scan method usually leads to low capture probability and the long time consumption, and count against the establishment of the communication link. So the GPS technology was adopted to complete the rapid acquisition, with the level and pitch reference sensor, and GSM network for wireless transmission was adopted. Finally, some acquisition experiments were done. The experimental results showed that the acquisition probability is 100% for fixed-point acquisition. For the simulated target acquisition, the increase of simulation speed could result in the increase of average time and the decrease of capture probability with minimum value of 60%; and the requirement for the link establishment can be satisfied for low-speed acquisition of the locomotive object.
