METHOD FOR REMOTE DETECTION AND TRACKING OF RADIO SILENT OBJECTS Russian patent published in 2020 - IPC G01S13/02 

FIELD: physics.

SUBSTANCE: invention relates to radio engineering and can be used in control systems of ground, sea and air space using direct and scattered radio signals emitted by multiple uncontrolled and controlled transmitters of radioelectronic systems for various purposes. Higher sensitivity is achieved by using new operations of masking interference compensation and coherent generation at each expected frequency of Doppler shift elements of three-dimensional space-frequency-time image from signals of all antennas of the array and their combination into a resultant image, instead of operations of incoherent summation of a set of two-dimensional frequency-time images formed from signals of separate antennae.

EFFECT: technical result is high sensitivity when detecting and tracking radio silent objects.
