Study of 2D localization using SIMO antenna

Abstract

A single input and multiple output (SIMO) antenna configuration is presented for real time data acquisition. The proposed approach can provide both range and angle information in a plane. A method of localization of multiple point objects (targets) in azimuthal plane is realized by employing one stationary transmitting antenna and dynamic receiving antennas positions. FMCW chirp signals are used as transmitting signals. A parametric analysis is carried out by varying the bandwidth of transmitted signal, number of samples and number of antennas on a linear array with equal inter-element spacing. Radial resolution of 0.4 feet and 0.23 feet is achieved for 2GHz and 6 GHz bandwidths respectively. The method is extended to identify multiple targets.
