Rf signal angle of arrival identification with adjustable antenna array

A system for identifying and visualizing a direction of arrival of radio frequency (RF) signals from an RF emitter, the system comprising:

• a test device comprising:
• a processor;
• and
• a display;
• and
• an apparatus comprising:
• an antenna array spacer;
• a first RF antenna movably mounted on the antenna array spacer;
• a second RF antenna movably mounted on the antenna array spacer, wherein the first RF antenna and the second RF antenna are to be moved to vary a distance between the first RF antenna and the second RF antenna, and wherein the first RF antenna and the second RF antenna are to detect RF signals;
• a camera to capture images in a field of view of the camera;
• and
• wherein the detected RF signals and the captured images are to be outputted to the test device, and wherein the test device comprises a processor to determine a direction of arrival of the detected RF signals and to cause an indication of the determined direction of arrival and the captured images to be displayed on the display.

A method for identifying and visualizing an angle of arrival of radio frequency (RF) signals from an RF emitter, the method comprising:

• receiving, by a processor of a test device, data from an apparatus, wherein the data comprises combined RF signals detected by a phased array of a first RF antenna and a second RF antenna over a range of phase shifts and at least one image captured by a camera;
• determining, by the processor, an angle of arrival of the combined RF signals from the combined RF signals over the range of phase shifts;
• causing, by the processor, the at least one image captured by the camera to be displayed on a display;
• and
• causing, by the processor, the determined angle of arrival to be displayed as an overlay on the displayed at least one image.
