FIELD: measurement technology.
SUBSTANCE: calculator of radial velocity of the moving object comprises a delay unit, a complex conjugation block complex multiplication, averaging unit, a phase calculation unit correcting measurement limits, a multiplier, a key calculation unit module, the first memory unit, a control unit, a threshold unit, a second memory unit , the timing, the first and second two-channel keys, additional averaging unit, an additional delay unit, an additional block of complex conjugation and additional complex multiplication unit connected in a certain way and performing between-period correlation processing raw samples.
EFFECT: improving the accuracy of measuring the speed due to the smaller number of functional transformation and expansion of the range of uniquely measured radial velocity while maintaining a clear distance measurement.
