Abstract
Methods to improve the performance of passive coherent location by non-reliance on a direct view of the signal source are described. Passive Coherent Location, or PCL, has become a promising technology as more computer-processing power has become generally available. Basically, most PCL techniques rely on comparing signal sources with their reflections from an object in order to determine the location of the object. However, this requires line of sight access from the receiver system to the signal source which may not always be practical and may limit the performance of the system overall. The techniques described herein do not require line of sight to the transmitter sources.
