Abstract:

Satellite thermal-vision monitoring requires both high geometrical resolution and frequent repetition of the imaging. However, high-angular-resolution satellite thermal viewers have a narrow viewing band and do not allow regular monitoring of territories. A resolution of this contradiction is proposed on the basis of the synthesis of the angular aperture of a scanning radiometer (thermal viewer). The results of laboratory and numerical experiments on the synthesis of the angular aperture of a thermal viewer are presented. It is shown that the synthetic angular aperture can be several times as large as the effective angular resolution of the thermal viewer without changing the viewing angle, and that the SNR is acceptable in practice.
