Automatic Target Recognition for SAR Images Based on Fuzzy Logic Systems

摘要

Automatic target recognition (ATR) generally refers to the autonomous or aided target detection and recognition by computer processing of data from a variety of sensors such as forward looking infrared (FLER), synthetic aperture radar (SAR), inverse synthetic aperture radar (ISAR), laser radar (LADAR), millimeter wave (MMW) radar, multispectral/hyperspectral sensors, low-light television (LLTV), video, etc. SAR is a coherent active imaging method that utilizes the motion of a radar mounted on a vehicle such as an aircraft (airborne SAR) or a satellite (spaceborne SAR) to synthesize the effect of a large aperture radar. Motivated by the unique character of fuzzy logic system, simultaneously handling numerical data and linguistic knowledge, and the promising knowledge-based approach, we propose an FLS-based approach to SAR ATR.
