ABSTRACT:
Target support structure for making bistatic radar cross section measurements. The support structure includes two parallel columns of circular cross section that may be coated with radar absorbing material. The rotational angle of the columns and the spacing therebetween are each adjustable to allow the bistatic reflections from each column to be phased to cancel each other at a selected bistatic angle and thereby minimize the background signal from the support structure.
