摘要: Parametric processing capability is added to a typical sensor so that target object can be more clearly distinguished from the background clutter in given scenery. A polarizer with several segments of different polarization orientations used improve sensor. The are sequentially advanced pass therethrough infrared radiation images pre-selected which then collected by respective polarized frame grabbers. Image circuit processes these yield difference between any pair orthogonal polarizations. In surveillance network, differences subsequently control center, such sensors connected, enhance distinction observed objects against suspended propagation medium.
