METHOD OF REMOTE MONITORING 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 applying masking interference compensation and coherent formation at each expected Doppler frequency and in each part of expected area of delays of elements of multidimensional space-frequency-time image from signals of all antennas of grid and their combination into resultant image instead of operations of incoherent summation of set of two-dimensional frequency-time images formed from signals of separate antennas.

EFFECT: high sensitivity when detecting and tracking radio-silent objects.
