| description | The invention discloses a foundational interference virtual aperture deformation monitoring radar system and a working method thereof. The foundational interference virtual aperture deformation monitoring radar system comprises a tripod, a two-dimensional turntable, a radar sub-system and a data display sub-system, wherein the radar sub-system is used for achieving scanning of a special region, and the two-dimensional turntable is used for global scanning. The working method comprises the steps of radiating broadband frequency modulation continuous wave signals at millimeter wave bands to a tunnel through uniform sparse linear arrays distributed at four edges of a rectangle by the radar sub-system, and receiving an echo signal to obtain initial radar echo data; performing first-time virtual aperture processing, namely MIMO processing, to achieve aperture expansion; executing distance to Fourier transform; performing second-time virtual aperture processing, namely forecast extrapolation, to further achieve ape |
