Abstract
Some parts of the emitted lights are scattered and reflected into the focal plane arrays (FPA) in one optical terminal by suspended particles in the outside wireless channel. The reflected lights are the interference sources for the signal detection and make its performance much lower. These interference lights also make the centrioding of light spots in the FPA inaccurate. In this paper, a recursive algorithm based on integrated control and adaptive filtering (ICAF) is proposed for the FPA signal detection. The ICAF method can reduce the noises in the received optical signal, and improve the detection performance effectively. The integrated control and adaptive filtering algorithm is simulated and validated in this paper.
