| Abstract: | Based on the fact that the motion(i.e.azimuth,elevation and their derivative velocities),amplitude and size of infrared target could be acquired simultaneously,a multi-feature association based approach is presented to track infrared dim moving target.The characters of the infrared imaging tracking system are first analyzed,and the motion,amplitude and size of target of interest are modeled as second order stationary random signals.The probability of motion,amplitude and size of measurement originated as ta... |
