Phase-Interferometry Based Direction-of-Arrival Estimation Using Coherent Software Defined Radios
This paper presents an experimental direction-ofarrival (DoA) system using two coherent NI USRP-2901 softwaredefined radios synchronized by a GPS-disciplined OctoClock, with one radio transmitting a narrowband tone and the other receiving on a two-element patch antenna array. Circular statistics on fifteen six-minute r...
