METHOD OF RADAR-TRACKING TARGET DETECTION AND DEVICE, FOR ITS REALISATION (VERSIONS) Russian patent published in 2009 - IPC G01S13/04 

FIELD: physics, radio.

SUBSTANCE: inventions concern field of radiolocation and can be used in radar stations at target detectionCarry out weight processing reflected from the purpose accepted electromagnetic oscillations with use n≥2 weight functions. Thus measure relations of levels of signals after weight processing, compare a signal after the weight processing providing obviously the greatest level of a signal, to a detection threshold, compare relations of levels of signals to their design values and make the solution on detection of the single purpose. In addition make the solution on detection of the group purpose if relations of level of a signal after the weight processing providing obviously the greatest level of a signal, to levels of signals after other views of the weight processing, measured in field of a lateral lobe of a signal of the found out purpose, differ from design values of these relations more than on the quantity erected for the single purpose and level of a signal in the field of this lobe exceeds a detection threshold.

EFFECT: detection of group target in case when the reflected signal from one purpose masks lateral lobes of the squeezed signal from other target.
