Innovative approach to signal processing of the small targets under complicated conditions including low-contrast and maneuvering targets with backgrounds is presented. Its essence is dealt with the use of intelligent solid-state photosensor, so-called photoelectric structures with memory (PESM). PESM is integrated multilayer heterostructure, which combines the main capabilities of photodetector, imager, memory media and parallel processor. Optical information signal is detected in photosensitive layer, recorded and stored as 2D charge pattern in memory layer, read out from reading layer, and processed due to charge, potential and electric field pattern interactions throughout the PESM layers. PESM performs such parallel image processing as summation, subtraction, contouring, convolution and correlation, which may be effectively applied to numerous tasks of diverse photonic systems. It is essential, that PESM performs such multifunctional operations in a real time without any additional processors and computers.
