A radiation source location technique includes focusing a plurality of receivers
(i.e., antennas) at the same location. At least one determined characteristic of
the radiation received at each receiver provides information regarding the source
of that radiation relative to each receiver. Determining a relationship between
the determined characteristics allows for determining when the source of radiation
is at the location where the receivers are focused. One example includes using
high directivity, narrow beamwidth antennas and time based markers from a wireless
digital communication signal for locating a mobile unit source of radiation.
