Abstract

A method for processing video signals in a digital image transformer in which, before conversion of the video data of the radar from polar coordinates into cartesian coordinates to be displayed on a television monitor, the distance sampling frequency is phase-locked to the sync pulses of the radar and the number of converted radials is limited to the resolution of the coder while satisfactory persistance is ensured and conversion errors are eliminated.
