Abstract :
The millimeter wave band is suitable for application in matching correlation systems, using radiometric sensors to form sensor maps owing to the wide weather possibility and ability to provide rather high spatial resolution for a comparatively small antenna size. The intensity of radiothermal radiation of this band differs with strong uncertainty caused by variations of seasonal, weather and other conditions and which are not conducive to probabilistic description. We proposed to use a reference map representation on various scales depending on a brightness variability degree for synthesis of zone-type object locating algorithms, which are resistant to brightness variations and based on a zoned model of sensor map
