Millimetre-Wave Radar System for 3D SAR Imaging: Experimental Results

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Millimetre-Wave (mmWave) based on frequency-modulated continuous-wave (FMCW) technique as applied to synthetic aperture radar (SAR) imaging has many potential applications related to security, automotive, mapping, medical, and surveillance. In this paper, a three-dimensional (3D) SAR imaging system at K band frequencies is presented and its effective performance is verified with the reconstructed images from a set of uniformly sampled data from the scene. The collected backscattered signals are measured over a 2D plane, in both horizontal and vertical directions, using a Nearfield Systems Inc. (NSI) measurement platform. This paper presents the complete details about the measurement steps along with the signal processing SAR technique for 3D image reconstruction. The presented work demonstrates the reconstruction of image for two different targets. The performance of the work is also verified with the 3D reconstructed image of one target in a concealed scenario
