The validation of radar cross section (RCS) prediction techniques against real measurements is crucial to acquire confidence in predictions when measurements are not available. We present the first results of a comparison on one dimensional images, i.e., radar range profiles. The profiles were measured of a target of opportunity, a Boeing 737, seen at broad-side aspect angles. At the same aspect angles and frequencies, profiles were predicted using the high-frequency RCS-prediction code RAPPORT in conjunction with a digitised model of the Boeing. Despite the assumptions and simplifications in both the prediction code and the aircraft model, an excellent agreement is observed
