Abstract: We present a localization and multiple access method for backscatter sensor networks based on synthetic aperture radar (SAR) techniques. Two sensor tags, each consisting of a wideband bow-tie antenna, a PIN switch, and an Arduino Nano, were designed for an indoor measurement over the 10-13 GHz band. With a synthetic aperture size of 0.6 m, the sensor tags can be imaged separately or in combination at ranges up to 4 m. A cross-range resolution of 8 cm and a range resolution of 4.6 cm were achieved at a range of 4 m, with localization errors of less than 4 cm.
