FIELD: radio engineering, communication.
SUBSTANCE: decision on detection of a signal from a target is made based on signal detection results in the same spatial element in amplitude mode and in moving target selection mode. In a viewing field element, in which the detection threshold is exceeded in amplitude mode, the ratio KI of signal/noise values is calculated in amplitude mode and in moving target selection mode, which is compared with a threshold value KP, calculated in advance for boundary radial velocity of the reflecting object, set based on allowable target losses. A signal detection decision is made if KI>KP.
EFFECT: high reliability of detecting signals from targets.
