A radar device such as the type which uses a non-constantly scanning radar antenna including a circuit arrangement for reducing interference due to ground reflection wherein an interference value is subtracted from the sampled received signal and wherein the interference value is obtained by recursively calculating from the sampled values with the use of a recursion factor which changes during the sampling sequence so as to reduce interference due to ground reflections and allow the detections of objects which are moving slowly in the radial direction.
