Simultaneous Rotation And Distance Measurement Using Multiband Circularly Polarized Radio Link, Adam Narbudowicz
Conference Papers
The paper proposes a method for simultaneous measurement of rotation and distance by using a multi-band circularly polarized radio links. The method is realized using a standard dual-band patch antenna, operating at 1.58 GHz and 2.27 GHz, with respective axial ratios of 1.7 dB and 1.0 dB. Both link distance and antenna rotation were varied from a reference position/orientation from -40 mm to +40 mm and from 0° to 360°, producing a total set of 125 samples. For a noiseless link the distance change and rotation were predicted with respective mean errors of 1.9 mm and 7.3°.
