Angle Servo Preamplifier.
Abstract
This document describes an angle servo preamplifier for use in the tracking antenna servo drive system of a precision tracking radar system. The angle servo preamplifier processes tracking error signals indicative of tracking antenna pointing errors with respect to a target. The preamplifier is comprised of an input differential amplifier stage, a phase control stage, a sample and hold stage and a power amplifier stage. In addition, interfacing circuitry is included for coupling the preamplifier to the azimuth/secant correction system of the tracking radar system. The sample and hold stage includes 'deglitching' circuitry for suppressing sampling/switching transients. And, to accommodate a bipolar tracking error signal while utilizing a single voltage supply, the power amplifier stage performs d.c. level translation. (Author)
