Appeal No. 98-3299
Application 08/335,331
method of locating a mobile radio communication transceiver in
an operating environment served by a wireless communications
system. [Figures 3 and 5 of the specification]. The claimed
invention can determine the location of a mobile transceiver
from a single line of bearing from a single sensor station.
The method and the apparatus claimed do not rely on a cross-
fix on location from another sensor station, rather they rely
on other known information defined as “collateral information”
in the specification. For example, such information can be
the topological maps previously stored in a processor unit of
the invention.
Representative claim 1 is reproduced as follows:
1. An apparatus for locating a mobile radio
communications transceiver in an operating environment served
by a wireless communications system, comprising:
at least a single sensor station having a directionally
sensitive receiving antenna to receive a radio signal from the
mobile transceiver,
a signal characterization processing unit for
determining, from the radio signal, at least one directional
line of bearing from the single sensor station to the mobile
radio transceiver,
a source of collateral information about the operating
environment of the mobile transceiver,
a multidimensional parametric correlation processing unit
