Abstract

A pulse radar for acquiring a target while rejecting the altitude line is described wherein a plurality of target reports from a scanning antenna are examined and rejected if the pattern of target reports at an apparent range extends along a scanning angle too large to be a valid target and selected if the pattern of target reports at a range extends along a limited scanning angle indicative of a target having a valid target size. Target reports rejected during a prior scan may be used as a basis for rejecting target reports of a current scan.
