Abstract

A novel UWB antenna system for the high-resolution near-field radar imaging has been developed. Digital footprint focusing and steering is realized using a linear receive array. The design has been verified experimentally. It has been demonstrated that the operational frequency band starts at 170MHz and ends at 3.3GHz at -10dB level. The array's footprint at a distance of 37cm can be electronically steered along the array up to a maximal displacement of 40cm from its centre. High-resolution radar images of a scene under investigation have been produced using footprint steering.
