HYBRID TDOA CLOSED FORM HYPERBOLIC AND SPHERICAL ITERATION GEO-LOCATION TECHNIQUE
Determining a signal emitter location involves receiving a signal of interest (SOI) at detection devices, generating a time stamp corresponding to the arrival of the SOI at each detection device, and communicating digital data samples and the time stamp to a time-difference of arrival (TDOA) compute...

Summary: | Determining a signal emitter location involves receiving a signal of interest (SOI) at detection devices, generating a time stamp corresponding to the arrival of the SOI at each detection device, and communicating digital data samples and the time stamp to a time-difference of arrival (TDOA) computer system. The TDOA computer system determines a TDOA of the SOI at the detection devices relative to an arrival time at a first one of the detection devices having an earliest time stamp. It determines a first solution to identify the emitter location in accordance with a first TDOA solution method. It evaluates the reliability of the first solution and selectively uses a second solution if the first solution is insufficiently reliable. |
