Microprocessor System for Controlling the Ohio State University Compact Range Target Support Pedestal

摘要

An advanced microprocessor-based stepper motor controller for the target support pedestal of the Ohio State University's compact backscatter measurement range has been constructed. The controller accurately controls target rotation and provides the target aspect angle to a host computer. Custom software for the controller implements a set of commands that provide variable rotational velocities and accelerations, as well as special stepping routines useful for the backscatter measurement process. The commands can be invoked remotely by a host computer or locally via a front panel keypad.
