Power-Based Direction-of-Arrival Estimation Using a Single Multi-Mode Antenna

open access: yes, 2017
Phased antenna arrays are widely used for direction-of-arrival (DoA) estimation. For low-cost applications, signal power or received signal strength indicator (RSSI) based approaches can be an alternative. However, they usually require multiple antennas,
