Abstract

PURPOSE:To expand and contract a display screen with its center as the starting point inveriably by controlling the expansion and contraction of the screen and off- center amount at the same ration on the display of radar information. CONSTITUTION:Some of the control amount of screen expansion-contraction control part 2 is inputted to off-center expansion-contraction control 5 and by its output, the off-center amount of off-center part 3 is expansion-contraction-controlled at the same ratio as a PPI dispaly signal from PPI display signal generating part 1. The PPI display signal and off-center amount are therefore expanded and contracted by the output of synthesizing amplifier 4 identically.
