Method and Apparatus for Detecting and Classifying Signals

A method for detecting signals, the method comprising:

• receiving energy waves at a first receiver system and a second receiver system;
• generating, by the first receiver system, first information using the energy waves received at the first receiver system;
• receiving, by the first receiver system, second information generated using the energy waves received at the second receiver system from the second receiver system;
• and
• identifying, by the first receiver system, desired information about a repetitive portion of a signal carried in the energy waves received at the first receiver system using the first information and the second information.

A receiver system comprising:

• a transducer system configured to receive energy waves and convert the received energy waves into an electrical signal;
• and
• a receiver configured to:
• generate information using the electrical signal;
• generate a number of stochastic histograms using the information generated;
• and
• detect and classify the signal using the number of stochastic histograms.

A cooperative detection and classification system comprising:

• a first receiver in a first receiver system in which the first receiver is configured to:
• generate first information in response to the first receiver system receiving first energy waves;
• and
• a second receiver in a second receiver system in which the second receiver is configured to:
• receive the first information from the first receiver;
• generate second information in response to the second receiver system receiving second energy waves in which the second energy waves include at least a portion of the first energy waves;
• and
• identify desired information about a repetitive portion of a signal carried in the second energy waves using the first information and the second information.

A cooperative classification system comprising:

• a receiver configured to:
• identify a first pulse train;
• receive a second pulse train identified by a different receiver;
• and
• match the first pulse train and the second pulse train within selected tolerances.
