Abstract
Provided herein are processes for locating wireless emitters. The processes provided may include use of an apparatus that includes a signal processing circuit configured to obtain a reference signal and a target signal, and process the reference signal and target signal to determine and output a reference channel value and a target channel value. The processes provided may also include use of an apparatus that includes a signal processing circuit configured to obtain a pair of reference channel values and a pair of target channel values, process the reference channel values and pair of target channel values to determine a phase-difference metric, and process the phase-difference metric to determine a set of spatial location coordinates. The set of spatial location coordinates may correspond to a location of a target emitter.
