Abstract
A method for direction finding of at least one stationary and/or moving transmitter comprises the following steps: measuring the signals emitted by each of the at least one transmitter at at least two different measurement points; determining the location of the measurements points at the time of the measurement; determining the bearings from the measurement points to each of the at least one transmitter; transferring the bearings to a pre-trained artificial neural network; and estimating the locations of the at least one transmitter by the artificial neural network. Further, a system for direction finding of at least one stationary and/or moving transmitter is shown.

A method for direction finding of at least one of a stationary transmitter and a moving transmitter, comprising the following steps:
- a) measuring said signals emitted by each of said at least one transmitter at at least two different measurement points;
- b) determining said location of said measurements points at said time of said measurement;
- c) determining said bearings from said measurement points to each of said at least one transmitter;
- d) creating a graphical representation of said bearings;
- e) transferring said graphical representation as said bearings or in addition to said bearings to a pre-trained artificial neural network;
- and
- f) estimating said locations of said at least one transmitter by said artificial neural network.
A system for direction finding of at least one of a stationary transmitter and a moving transmitter comprising:
- at least one of at least two stationary direction finding units with an antenna each and at least one movable direction finding unit with an antenna;
- a bearing module configured for determining said bearings from said antenna to each of said at least one transmitter;
- and
- a pre-trained artificial neural network configured for estimating said locations of said at least one transmitter based on said determined bearings,
- wherein said system is configured to:
- a) measure said signals emitted by each of said at least one transmitter at at least two different measurement points;
- b) determine said location of said measurements points at said time of said measurement;
- c) determine said bearings from said measurement points to each of said at least one transmitter;
- d) create a graphical representation of said bearings;
- e) transfer said graphical representation as said bearings or in addition to said bearings to a pre-trained artificial neural network;
- and
- f) estimate said locations of said at least one transmitter by said artificial neural network.
