FIELD: physics.
SUBSTANCE: invention relates to passive radio-thermal-location systems (RTLS) for monitoring millimeter wavelengths, intended for generating a radio thermal image of objects in the field of view. Technical result is achieved by applying a method for generating a radio thermal image, which consists in scanning the survey zone by a radiometer antenna in azimuth and at elevation angle, forming the observation matrix Y according to the scanning results, its processing by the R1 recovery operator and obtaining matrix Y1= R1[Y] of the radio thermal image, wherein the radiometer is combined with the camera, which gives matrix X1 of the optical image of the field of view at the central position of the antenna. In matrix X1, the scale is replaced by correspondence to the scale of matrix Y1 and matrix X2, which, with the help of operator R2 is obtained and subjected to segmentation operations by contrast of the sum of the amplitudes of the corresponding elements of matrices Y1 and X2, taken with certain weight coefficients, and label matrix S = R2[Y1,X2] is obtained, where number s of the segment is assigned to each i-th, j-th element to which it belongs. Then, by averaging the elements of matrix Y1 with label s, the average radiometric amplitude of each s-th segment is determined and this amplitude is assigned to the elements of matrix X2 with the same label s, as a result according to matrix X2 a radiometric image matrix with an increased spatial resolution is obtained.
EFFECT: achieved technical result is an opportunity on the basis of a scanning radiometer to form a radio thermal image of the field of view with a spatial resolution corresponding to the dimensions of the elements of the desired image matrix.
