Abstract

AVTIS is a compact portable remote sensing instrument originally designed for ground based surveying of active volcanic lava domes. Its primary mode of operation is active, using a monostatic 200mW 94GHz FMCW radar. The 94GHz signal is provided via a multiplied 7GHz source. Careful choice of a low-noise, highly linear 7GHz source has extended the range of the radar to at least 7km whilst retaining a range resolution of 1m. We will present results showing the range resolution and discrimination of separated targets for both natural topography at far ranges (>1km) and man made targets at close ranges (<1km). For close range imaging, the signal bandwidth can be increased to improve the range resolution allowing finer quality imagery to be retrieved.
