FIELD: radio engineering and communications.
SUBSTANCE: invention relates to infrared detection, namely to passive monitoring systems of objects with the help of multichannel radio-thermal radar stations or radiometers with scanning antennas. A multichannel radio-thermal radar station with several combined antennas, which have different characteristics of directional patterns, receives signals in different frequency ranges. Antennas scan the area of view, moving along the azimuth and elevation angle. As a result of scanning and primary processing of the received signals in several measuring channels (in terms of the number of antennas), thermal radio image arrays are formed. A positive effect is achieved through multiplying the thermal radio image arrays by certain coefficients and then through jointly processing of the arrays with the help of image reconstruction operations.
EFFECT: increasing the spatial resolution of images in the thermal radio image arrays equally for all channels while maintaining the temperature characteristics of the frequency ranges.
