摘要 |
Disclosed is an apparatus and method for locating a transmitter. The apparatus comprises an antenna, a receiver and a memory adapted to store the plurality signals received by the receiver and antenna. The plurality of signals represents a plurality of data points relating to the position of the transmitter as measured at a plurality of unique locations. The location of the transmitter is calculated using the plurality data points. The plurality of data points may represent a measured frequency of a signal transmitted by the transmitter a direction of the transmitter or any other type of data. The method may comprise utilizing the Doppler shift rate of change of an assumed transmitted frequency to calculate a conical surface. The calculated intersection of a plurality of conical surfaces to defines the location of the transmitter.
