Abstract
Способ повышения разрешающей способности радиотепловых изображений, заключающийся в том, что при наблюдении за поверхностью или воздушной обстановкой с помощью сканирующей радиотеплолокационной станции (РТЛС) с одной антенной, диаграмма направленности (ДН) которой описывается функцией с разделенными переменными, последовательно смещают антенну по азимуту и углу места соответственно на величину (2n+1)-й и (2m+1)-й части ширины ДН построчно в зоне обзора, измеряют амплитуды приемных сигналов при каждом i, j-м положении антенны и формируют из этих амплитуд матрицу измерений Y11 с элементами y(i, j), , , которую далее обрабатывают, ! отличающийся тем, что увеличивают число каналов и формируют матрицы измерений K(K>1) основных каналов Y11, Y22, …, YKK, далее с помощью синтеза или включения К2-К дополнительных каналов формируют матрицы измерений Yqk, , , q≠k смешанных каналов и составляют из всех матриц блочную матрицу Y, затем умножают матрицу Y слева и справа на блочные матрицы весовых коэффициентов НA и НB, вычисляемые заранее по определенной методике, тем самым получают матрицу изображения всей I×J-зоны обзора с повышенным в несколько раз разрешением по угловым координатам.A way to increase the resolution of thermal thermal images, which consists in the fact that when observing a surface or airborne environment using a scanning radio-thermal radar station (RTLS) with one antenna, the radiation pattern of which is described by a function with separated variables, the antenna is successively shifted in azimuth and angle places, respectively, by the value of the (2n + 1) th and (2m + 1) th parts of the beam width line by line in the field of view, the amplitudes of the receiving signals are measured at each i, jth antenna position and formed from their amplitudes, the measurement matrix Y11 with elements y (i, j),,, which is further processed,! characterized in that they increase the number of channels and form measurement matrices K (K> 1) of the main channels Y11, Y22, ..., YKK, then, using synthesis or inclusion of K2-K additional channels, the measurement matrices Yqk,,, q ≠ k of mixed channels are formed and make up the block matrix Y from all the matrices, then multiply the matrix Y on the left and right by the block matrices of weighting coefficients HA and HB calculated in advance by a certain technique, thereby obtaining an image matrix of the entire I × J viewing area with a several-fold higher resolution angular coordinates.
