Target Detection Method of Focal Plane Array Search System
In accordance with the features of the area infrared focal plane array (AFPA),an new focal plane array search system is introduced.The system′s innovation lies in that the AFPA′s rotation will increase the number of the target detection effective pixel,and this will increase the target detection signal to noise ratio (SNR).Firstly,the parameters of focal plane array search system′s and it′s work process,then deduces the system point spread model are described and the imaging characteristics of the target is analyed.Secondly the target detection algorithm is described and analyzed,and the signal processing hardware architecture is introduced.Finally the experimental results show that the focal plane array search system has high target detection probability,and can detect dim target in the strong clutter enviroment.
