Patent number: 9322898Abstract: An apparatus and method for estimating the direction of an RF signal is provided. The apparatus includes an antenna for receiving an RF signal. An electronic compass is configured to, as a pointing direction of the antenna is varied, generate information about pointing directions and pointing angles corresponding to variations in the pointing direction of the antenna. A control unit determines RSSI values at respective pointing angles of the antenna based on a received signal of the antenna and information of the electronic compass depending on the variations, extracts a maximum RSSI value from the RSSI values at respective pointing angles, and stores the maximum RSSI value and a pointing direction corresponding to the maximum RSSI value. A display unit displays the RSSI values at the respective pointing angles and a trajectory of the RSSI values at respective pointing angles under control of the control unit.Type: GrantFiled: June 14, 2013Date of Patent: April 26, 2016Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Jong-Kyu Kim, Hui-Rae Cho, Jin-Gak Jang, In-Ho Hwang, Chun-Soo Kim
