Geolocation method for detection and tracking of maneuvering emitters

A computing system, comprising:

• a memory configured to store registration information of a computing device;
• and
• a hardware processor communicatively coupled to the memory, the hardware processor configured to execute:
• receiving, using radio frequency (RF) collectors communicatively coupled to the computing system, RF signals from a target object;
• converting the RF signals of the target object to In-phase and Quadrature (I/Q) data;
• determining navigation data of each RF collector, wherein the I/Q data of each of the RF collectors are paired;
• applying processing functions on the paired I/Q data of the RF collectors;
• determining, using the paired I/Q data of the RF collectors, one or more of time difference of arrival (TDOA) measurement data and frequency difference of arrival (FDOA) measurement data between each pair of the RF collectors;
• converting the one or more of the TDOA measurement data and the FDOA measurement data between each pair of the RF collectors and the navigation data of each RF collector to message data;
• estimating a trajectory of the target object based on a confidence measure of the one or more of the TDOA measurement data and the FDOA measurement data;
• and
• using the estimated trajectory of the target object for displaying on a display device associated with a computing device.

A non-transitory computer-readable medium storing instructions that, when executed by a processor of a computing system, causes the processor to execute:

• receiving, using radio frequency (RF) collectors communicatively coupled to the computing system, RF signals from a target object;
• converting the RF signals of the target object to In-phase and Quadrature (I/Q) data;
• determining navigation data of each RF collector, wherein the I/Q data of each of the RF collectors are paired;
• applying processing functions on the paired I/Q data of the RF collectors;
• determining, using the paired I/Q data of the RF collectors, one or more of time difference of arrival (TDOA) measurement data and frequency difference of arrival (FDOA) measurement data between each pair of the RF collectors;
• converting the one or more of the TDOA measurement data and the FDOA measurement data between each pair of the RF collectors and the navigation data of each RF collector to message data;
• estimating a trajectory of the target object based on a confidence measure of the one or more of the TDOA measurement data and the FDOA measurement data;
• and
• using the estimated trajectory of the target object for displaying on a display device associated with a computing device.
