Abstract: A method of locating a mobile station is provided. In the present invention, the mobile station is capable of communicating with at least three base stations, each having at least two antennas. To estimate the location of the mobile station, the distance between the mobile station and each base station is calculated based on the time of arrival (TOA) of a mobile station signal at the base station, a first estimated MS location area is defined as an overlap area of circles of which the radiii are the distances between the MS and the base stations. Then, the location of the mobile station is estimated based on the time of signals received through the two antennas of each base station and based on the angle between the antennas of each base station and the mobile station. Here, the angle is calculated from the phase difference between the received signals and a communication frequency of the signals. A second location area is defined as an area defined by lines connecting the base stations to the mobile station. Then, the MS is determined to be located in a common area of the first and the second location areas.

Abstract: System for determining the position of radar transmitters where the system includes at least one information center with associated cells and means of communication between the information center and the cells with a restricted transfer rate utilising existing infrastructure in the country, such as for example a national telephone network and also mobile telephone networks and their base stations. Each cell includes at least one sensor in order to be able to detect radar signals. Leading edges of pulses in the radar signals are detected and time-marked after which they are sorted according to PRI (Pulse Repetition Interval). The time of arrival for the first pulse in a pulse train is calculated and data reduced by modulo calculation to a value that as a maximum is the propagation time difference for pulses between two cells in a pair of cells/sensors that are used together for calculating the bearing. Bearings calculated from at least two pairs of cells are correlated in the information center which thereafter calculates the position of the radar transmitter.

Abstract: A system for achieving improved angular resolution with baseband radar systems which includes dual baseband receivers and a correlator or tapped transmission line therebetween. The tap on the transmission line at which pulses received by each receiver coalesce determines the angular location of a target with an angular resolution that is proportional to the ratio of the pulse width to the receiver separation.
