Abstract:

This report discusses factors affecting the performance of an electrostatic Plan Position Indicator PPI and methods of compensating for various errors in presentation. It includes descriptions of various systems for obtaining PPI traces by purely electronic means. One system eliminates the selsyn follower mechanism at the indicator by obtaining the antenna-position information from a sine potentiometer or Autosyn resolver phase-amplitude detector in such form that it can directly actuate the sweep generator.
