Abstract
A method and an apparatus are provided for performing passing sensing using wireless digital communications. The wireless digital communications are frame-based with a predefined frame structure. The method includes receiving a reference signal into to a reference channel, wherein the reference signal comprises a direct version of a radio frequency transmission as part of said wireless digital communications; receiving a surveillance signal into a surveillance channel; detecting and extracting portions of the reference signal corresponding to data transmissions based on said predefined frame structure; extracting portions of the surveillance signal corresponding to the extracted portions of the reference signal; performing a cross-correlation on the extracted portions of the reference signal and the surveillance signal to determine a range-Doppler surface; and providing a real-time display of said range-Doppler surface and/or of information derived therefrom.
