Abstract	A microwave radome gauge (MWRG) design for verification of the microwave properties of a radome is presented. A mathematical model of the gauge is developed, and expected results are calculated and compared to measured results. These results indicate that the MWRG is relatively insensitive to its flange (choke) dimensions and the radiation resistance of the slot antenna formed by the flange and conducting foil that enclose the radome. The resonant frequency of the device shifts approximately=0.1% for a 1% change in the radome's core thickness, or dielectric constant, and approximately=0.01% for a 1% change in sheet thickness. The tool is virtually insensitive to a change in loss tangent of radome sheet material. Use of the MWRG shows that this test procedure is a satisfactory method of verifying an RF window's performance prior to shipment and installation with the antenna assembly. Experience with the measurement of standard panels indicates consistency in manufacturing and of the test method and equipment. The MWRG has also demonstrated its ability to detect defects in the RF window; that is, it accurately located bleeder strips and overlap areas between adjacent sheets.<>
