METHOD FOR SECRETIVE MONITORING OF RADIO SILENT OBJECTS Russian patent published in 2020 - IPC G01S13/02 G01S13/87 

FIELD: radio equipment.

SUBSTANCE: invention 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. Efficiency improvement is achieved due to use of new masking interference compensation operations, as well as operations of formation of a set of small-size single-frequency matrix signals of the complex phasing function for various parts of the expected delay region instead of a set of higher-dimensional double-frequency matrix signals of a complex phasing function for a full region of expected delays.

EFFECT: technical result is high efficiency (sensitivity and speed) of stealthy tracking of radio-silent objects.
