Abstract
I et følgesystem for innretting av en reflektorantenne (2) mot en elektromagnetisk strålekilde (3), med en reflektor (4) og en foran reflektoren plassert, roterbar subreflektor (5), er subreflektoren (5) skråstilt relativt reflektoren (4) med en offset-vinkel (10).Ved vinkeldreininger av subreflektoren (5) kan det tilveiebringes triggersignaler som kan sammenlignes og benyttes for en signalmåling av den reflekterte stråling.
