RADAR Russian patent published in 2001 - IPC

FIELD: radio detection and ranging. SUBSTANCE: instead of the coarse azimuth determination unit introduced are the automatic bearing tracking unit and the range corrector consisting of: an envelope amplitude-to- code converter unit, permanent storage, on-line storage, divider and multiplier; the second input and the output of the automatic bearing tracking unit are connected to the receiver output, and via the first input of the range corrector- to the first input of the on-line storage, having the second input and output connected respectively: via the permanent storage, via the envelope amplitude-to-code converter unit, via the second input of the range corrector to the mentioned output of the receiver and to the first input of the divider, whose second input and the output are respectively connected to the output of the permanent storage and to the first input of the divider, whose second input and the output are connected respectively to the output of the permanent storage and to the first input of the multiplier, having the second input and output respectively connected via the third input of the range corrector to the output of the envelope amplitude- to-code converter unit and to the third input of the range finding unit. EFFECT: enhanced accuracy of range finding and enhanced bearing resolution. 1 dwg
