Real-time RF signal visualization device
First Claim
Patent Images
1. An instrument for detecting a direction to a source of RF energy relative to the instrument and indicating the direction to a user, comprising:
- an antenna;
a receiver coupled to the antenna generating a signal indicative of received RF energy from the source of RF energy;
an imager for gathering image data from a scene of physical objects and producing a signal indicative thereof;
a processor receiving the signal indicative of received RF energy, determining the direction to the RF source based on the signal for a predetermined period of time representative of a time related to the produced image data signal, and combining the direction of received RF energy with image data received from the imager representative of the predetermined period of time;
a sensor for determining roll, pitch, and yaw coordinates of the instrument; and
a display coupled to the processor for displaying a direction parameter indicative of the RF direction and the determined roll, pitch, and yaw coordinates with respect to the image of the scene corresponding to the predetermined period of time.
