Embodiment Construction

[0033] refer to figure 1 , discloses a diagram of a specific embodiment of a system for detecting the position of a transmitter and is generally designated 100 . The system 100 may include a transmitter 106 and a device 102 (eg, an unmanned aerial vehicle (UVA)). In particular embodiments, the device 102 is in communication with a control device 150 (eg, a ground control device). In particular embodiments, device 102 may have intermittent communication with control device 150 . In alternative implementations, device 102 may not communicate directly with ground control devices (eg, control device 150 ). In this embodiment, device 102 may operate autonomously (eg, fly, navigate, or both). For example, autonomous 102 may operate using an autopilot to traverse a flight path to preprogrammed or self-selected points.

[0034] Apparatus 102 may include a body 104 coupled to a controller 142 and a signal processor 144 . Apparatus 102 may also include a plurality of rotors (eg, ro...

Abstract

A method includes controlling a plurality of rotors to cause a plurality of antennas to traverse a flight path. Traversing the flight path includes concurrent translation of a body in a horizontal plane and rotation of the body about an axis. The plurality of rotors is coupled to the body. The method also includes, while traversing the flight path, receiving a first phase measurement of a first signal via a first antenna of a plurality of antennas and receiving a second phase measurement of the first signal via a second antenna of the plurality of antennas. The method further includes determining position information related to a location of the transmitter based at least in part on the first phase measurement and the second phase measurement.

Description

Background technique [0001] The present disclosure generally relates to systems and methods for transmitter position detection. Determining the geospatial location of a transmitter (eg, a cellular telephone) has applications in civilian search and rescue, law enforcement, and military settings. Phase measurements of signals transmitted by a transmitter and received by two or more antennas can be used to determine an estimated location of the transmitter. For example, an antenna at a fixed location can receive the signal, and an estimated location of the transmitter can be determined based on phase measurements of the signal. Phase measurements of signals received at fixed spatial locations do not enable the transmitter's position to be estimated with high accuracy. Contents of the invention [0002] Systems and methods for transmitter position detection are disclosed. The disclosed embodiments enable several phase measurements of signals received by antennas at different ...
