ALTITUDE DETERMINATION DEVICE Russian patent published in 1998 - IPC

FIELD: radiolocation; air objects search and tracking systems. SUBSTANCE: device has unit of envelope amplitude determination and main storage. Receiver output is connected to first input of main storage through unit of envelope amplitude determination. Second, third and fourth outputs of main storage are connected, respectively, to output of unit which determines time mismatch between scanning origin and center of envelope, and to third and fourth outputs of unit of phasing control during beam reciprocation. Main storage output is connected to second input of subtracter. EFFECT: reduced observation time. 2 dwg
