A 94GHz real aperture 3D imaging radar

Research output: Chapter in Book/Report/Conference proceeding › Chapter

Abstract

The AVTIS radar developed in St Andrews is a ground-based, portable, 3D imaging radar designed for high resolution terrain mapping. The 94GHz radar uses FMCW modulation and employs a mechanically scanned monostatic antenna configuration, achieving a maximum range of ∼7km with sub-metre range resolution. We discuss the significant factors which affect the imaging performance such as source phase noise and non-linearity, antenna pattern quality, and surface extraction algorithms. Field testing results gathered at a local quarry are presented to illustrate the effects of antenna pattern quality on the digital reconstruction of terrain.
