High maneuverability and stealthy-ability are the main developing directions of present weapon systems, such as ballistic missile, cruise missile, long-range fighter-bomber, etc, and they often emerge as moving targets in the sensed images. Since rapid reaction and far-distance detecting ability is the unique efficient way to countermine these weapons, it is of great importance to realize real-time detection of moving targets on surveillance satellites. This thesis majors in the detection of small moving ta...
