Abstract

The electrical test of aircraft radomes are usually made on an outdoor far field test range, and are both extensive and expensive, often requiring days of effort per radome. A new method of testing is posed where point-by-point microwave reflectometer (amplitude and phase) data are used, in conjunction with a predictive algorithm, to extrapolate equivalent wall layer parameters at the measurement point. These data are then incorporated in a ray trace computer code to predict full radome BSE and loss contours without the need for a full outdoor test range; significant cost and schedule savings accrue. Millimeter wave reflectometer data are also shown to be potentially valuable in detecting and characterizing certain types of defects.
