Electrical Thickness Measurement by a Single-Horn Method
-
Description
-
In order to correct the boresight error of a radome, it is necessary to start with a radome whose walls are uniform in electrical thickness over any given cross section taken perpendicular to the radome axis. It is a difficult problem to manufacture radomes of uniform electrical thickness; therefore, it is desirable to be able to measure the electrical thickness of the radome wall. This measurement may then be used in a control procedure in the manufacture or subsequent correction of the radome. The most common method of making this measurement is by means of a two-horn interferometer. This method is in general satisfactory; however, particularly for large radome of a high fineness ratio, the mechanical problems of maintaining the separation of two horns, one inside and one outside the radome, to close tolerance becomes very difficult. Thus, it would be desirable to obtain the electrical thickness of the radome wall by means of a reflection measurement using only a single horn placed outside the radome. Such an apparatus has been designed and constructed at Hughes Aircraft Company and is the subject of this paper.
