摘要

2053872 9013926 PCTABS00002 A radar reflecting target comprises a plurality of reflecting elements (10) spread along at least one linear physical dimension of the target, the elements (10) being differingly spaced in the direction normal to said dimension so that respective retro-reflections by the elements of radio frequency energy from a remote source on a line of sight at an angle to said dimension, have differing phases and tend to cancel each other out. The invention may be applied to single or two dimensional surfaces on such vehicles as ships or aeroplanes.
