Abstract

An RF network analyzer normally uses a reference port to excite a device under test. The return from the device is compared in amplitude and phase to the reference to characterize the S-Parameters (reflection and transmission) of the device under test (DUT). In this case, the DUT was 30 meteres of limestone above a mine in Northwest Pennsylvania, which was being tested for dielectric constant and attenuation at 3-33 MHz as part of a ground penetrating radar development effort. This paper describes the test configuration using a wideband fiber optic link for the reference signal, and provides plots of the experimental results.
