Abstract
Single antenna direction finding is performed by physically moving a device to different device positions. As the device is physically moved, signal processing hardware within the device is used to make a plurality of signal response measurements of a wireless signal detected by a single antenna of the device. The wireless signal emanates from an object. The plurality of signal response measurements are made by sampling signal response at a plurality of sample times. An inertial measurement system makes a plurality of inertial measurements at the plurality of sample times. The plurality of signal response measurements and the plurality of inertial measurements are used to produce a virtual response array vector. The virtual response array vector is used to calculate a direction of arrival from the object to the device.
