OBJECT DETECTION DEVICE Russian patent published in 2011 - IPC G01S13/04 

FIELD: radio engineering.

SUBSTANCE: in signal detection device the signal processing unit is made of N (N>2) identical channels independent of each other; the number of receiving antennae is determined as per the number of channels; each receiving antenna is identical to others and independent of other receiving antennae and connected to the appropriate channel of signal processing unit; transmitting part has information output, and receiving part also includes unit for determining the current diffraction-interference pattern, comparing unit of diffraction-interference patterns, information storage unit, unit for determining coordinates and velocity vector, and decision-making and control block. The above devices are connected to each other in certain manner.

EFFECT: possibility of monostatic location of receiving and transmitting parts of the proposed device, higher location accuracy of objects owing to using the interfering factor caused by double diffraction of radar signal on the target object.
