Techniques are disclosed that allow for the detection and locating of RF emitters. The technique includes recording emitter signals of interest received from the search area via an antenna array and a phase coherent receiver, wherein all frequency conversions carried out by the phase coherent receiver are performed in a phase coherent fashion across all the channels. The technique further includes identifying subspace of each channel using singular value decomposition (SVD), analyzing the subspace of each channel for the presence of a target signal, and direction finding and/or geolocating the target signal.

Detecting and locating RF emissions using subspace techniques to mitigate interference

A convenient handheld locator is provided for locating an item in an urban environment in which the locator is programmed to search for and locate specific items, with the detected item being displayed on the locator as to its identity or name, also displaying where the item is relative to the locator, as to position and range.
