FIELD: radar engineering.
SUBSTANCE: invention relates to systems of radar non-contact control of concrete and reinforced concrete products and structures. A broadband radar with a synthetic aperture MIMO-format antenna array is proposed, in which the microcontroller is connected by the first bus to the control input of the switch, the second bus to the control input of the direct digital frequency synthesis unit, the third bus to the master input of the amplifier with a programmable coefficient amplification, the output of the direct digital frequency synthesis unit is connected to the first input of the mixer, and through the amplifier and the matcher to the input of the switch, the output of which is connected to the MIMO-format antenna array, the output of which is connected through the switch through the first band-pass filter and the amplifier to the second input of the mixer, the output of the mixer through the second band-pass filter and a programmable gain amplifier is connected to the input of the microcontroller, the output of which is connected to a personal computer and a printer.
EFFECT: increased resolution and speed of the system.
