  • System and method for obtaining radio frequency (RF) signal data
    Patent number: 10764718
    Abstract: A system includes a plurality of mobile monitor setups, each mobile monitor setup connected with a vehicle. Each mobile monitor setup includes an omnidirectional antenna, a global positioning system (GPS) signal antenna configured to receive GPS signals and a receiver configured to obtain a plurality of radio frequency (RF) measurements. The plurality of RF measurements are swept across one or more frequency bands and each RF measurement is time stamped and location stamped based on received GPS signals.

  • System and method for RF direction finding using geographic RF channel power measurements
    Patent number: 10505648
    Abstract: A method of estimating a location of an interference signal source includes using a first antenna configured to receive a signal from the interference signal source and using a second antenna arranged proximate to the first antenna and configured to receive global positioning system (GPS) signals. An initial trend in variation in power of a received signal from the interference signal source is determined relative to a position of the second antenna, wherein upon determining the initial trend, the initial trend is a current trend. In an iterative manner, the second antenna is directed to be repositioned. A secondary area associated with a lack of power measurement outside of an area traveled is identified and a further repositioning of the second antenna is determined to reduce the secondary area. An estimate of the location of the interference signal source is then determined.

  • Systems and methods for determining a location of a signal emitter based on signal power
    Patent number: 9560537
    Abstract: A method of estimating a location of an interference signal source includes using a first antenna configured to receive a signal from the interference signal source and using a second antenna arranged proximate to the first antenna and configured to receive global positioning system (GPS) signals. An initial trend in variation in power of a received signal from the interference signal source is determined relative to a position of the second antenna, wherein upon determining the initial trend, the initial trend is a current trend. In an iterative manner, the second antenna is directed to be repositioned and a current trend in the peak measurement in power is observed until an estimate of the location of the interference signal source is determined.
