Abstract : This document discloses a method and apparatus for a passive station to locate itself relative to a stationary or moving transmitting station transmitting a narrow pulsed scanning beam by utilizing reception of pulses directly from the transmitting station and reception of reflected pulses from a set of scatterers. A method and means for determining a bearing from the transmitting station and a method and means for determining a range to the transmitting station is disclosed utilizing a set of differential times, the times for a pulse from the transmitting station to travel to each scatterer and then to the passive station,a set of angles lying between a line connecting the transmitting station and passive station and a set of lines connecting the transmitting station and the set of scatterers and a set of angles lying between a link connecting the passive station and the transmitting station and the set of lines connecting the passive station and the set of scatterers.
