System for receiving communications

A system for determining directions to and outputting communications from at least one source contributing to a source wave field in a propagation medium, the system comprising:

• a structure placed within the propagating medium, the structure incorporating multiple transducers whose output channels output simultaneous signals consistent with temporal and spatial Nyquist criteria that represent and characterize fluctuating charge and current densities within the structure;
• a directional model defining a map between the direction to each possible source in the propagation medium and the set of output signals created by the fluctuating charge and current densities generated by the waves emanating from each possible source;
• detection criteria for determining the presence of signals from at least one source in the propagation medium in each output channel;
• a sector model constructed from the directional model and detection criteria, the sector model defining collections of possible source directions and collection weights for each output channel;
• and
• a processor communicatively coupled to the signals from the output channels and configured to use the signals from the output channels, the detection criteria, and the sector model collections and weights to identify and output probable collections of directions possibly containing the at least one source in the propagation medium and/or outputting the communications from the at least one source.

A method for outputting communications to at least one receiver via a physical wave field in a propagation medium, the method comprising:

• providing the directions to the at least one receiver,
• providing a structure placed within the propagating medium, the structure incorporating multiple transducers generating consistent with temporal and spatial Nyquist criteria fluctuating charge and current densities within the structure from the transducer input signals;
• providing a directional model relating input signal sets to the propagation directions of consequent fields generated by said fluctuating charge and current densities within the structure;
• providing a sector model constructed from the directional model, the sector model defining collections of possible receiver directions and collection weights for each channel,
• providing a processor communicatively coupled to the structure's channel inputs and configured for generating their signals;
• and
• using the processor, the directions to at least one receiver, at least one possible channel input signal and the sector models collections and weights to output communications to the at least one receiver.

A system for outputting communications to intended receivers via a wave field in a propagating medium, the system comprising:

• providing the directions to at least one receiver,
• a structure placed within the propagating medium, the structure incorporating multiple transducers generating consistent with temporal and spatial Nyquist criteria fluctuating charge and current densities within the structure within from the transducer input signals;
• a directional model relating sets of structure input signals to the propagation directions of fields generated in the propagating medium by the structure's charge and current density fluctuations;
• a communications interface for the intended receivers;
• and
• a processor communicatively coupled to the structure's transducer channel inputs and configured for generating their input signals, the processor being further configured to use the receiver directions and the directional model to generate the channel input signals needed to convey the communications to the at least one receiver.
