Abstract

Interferometry has gained importance as a remote sensing technique to study topography, topographic change and volume and surface scattering properties of various natural targets. Interferometric radars rely on the ability to accurately measure amplitude and phase between signals received on two spatially separated antennas. The accuracy required for interferometric measurements place tight constraints on the performance of the radar hardware. This thesis details the development, construction and testing of a two-stage, two-channel Ku band downconverter ( also referred to as Dual Channel Downconverter or DDC)- which forms the core of the interferometer - to meet the requirements to make highly accurate interferometric measurements.
