Аннотация: In multichannel radio engineering systems based on multiple-inputmultiple-output (MIMO) technology, one of the main problems is the task ofdigitizing a large data flow received on each receiving channel of the system, since a large number ofsamples of the analog-to-digital converter (ADC) significantly increases the volume of the informationflow from the ADC to the computer. One of the approaches that would help to reduce this flow may bethe use of an analog-to-information converter (AIC) based on the theory of compressed sampling, whichcan significantly reduce the data flow transmitted to the computing device due to digitization with asampling frequency lower than twice the maximum frequency of the signal itself. In this paper, thepossibility of using AIC in a MIMO radar of the Ku frequency range based on the technology ofcontinuous radiation with linear frequency modulation is considered. The paper presents modeling, aswell as experimental development of the proposed solutions, during which the possibility of reducing theADC sampling frequency from 4 to 1 MHz at maximum frequencies of the received signal of 2 MHz isshown
