Abstract

This paper presents a data fusion algorithm combining a 24 GHZ radar and a 94.5 GHz radiometer for 3D image. Three trihedral reflectors are tested as multiple targets. Based on a conical scanner, the radar azimuth-range image and radiometric azimuth-elevation image are firstly obtained and preprocessed respectively. Then the common dimension of azimuth is made use of to align two images and synthesize a 3D image, where the positions, ranges and combined intensities of the targets are illustrated. Outdoor tests and experiment results demonstrate the effectiveness of the idea.
