The pulse is reflected from the objects encountered on the signal path and is received by the receiving active phased array antenna. The received signal is amplified and detected by a phase detector.\u003c\/p\u003e \u003cp align=\"left\"\u003eIf the object moves, the frequency of the signal reflected from this object changes to the Doppler frequency, and an alternating voltage with the Doppler frequency appears at the output of the phase detector. The voltage is converted into digital form, averaged over a certain period of time; the spectrum of the signal is calculated; the spectral components corresponding to the movement are marked. Their value is compared to the set detection threshold and there is a mark in the given viewing sector on the range corresponding to lag time of the reflected pulse, the color intensity of which is proportional to the amplitude of the spectral component. The spectrum of the signal is calculated according to the data obtained within 1.5 seconds and corresponds to the signals reflected from moving people in the frequency range of 1-8 Hz.\u003c\/p\u003e \u003cp align=\"left\"\u003eIn addition, according to the data obtained, within 12 seconds the spectrum of the signal is detected in the frequency range of 0.1-0.5 Hz, which corresponds to a change in
