ABSTRACT:
A method and apparatus for detecting emitter movement. The method and apparatus generally include acquiring a measured signal characteristic corresponding to a signal emitted from an emitter, estimating a signal characteristic corresponding to the signal, and comparing the measured and estimated signal characteristics to determine if the emitter is moving. Such a configuration enables a rapid and accurate detection of emitter movement without requiring multiple measurements, complex systems, or time-consuming calculations.
