Method of transmitting and receiving signals in separate frequency parts to reduce undesired components

Claim 1

A METHOD OF TRANSMITTING AND RECEIVING SIGNALS UTILIZING A TOTAL SIGNAL BANDWIDTH OF MORE THAN ONE HALF OCTAVE AND EMPLOYING A TRANSDUCER ARRAY TO DISCRIMINATE BETWEEN RECEIVED SIGNALS HAVING DIFFERENT APPARENT VELOCITIES ACROSS THE ARRAY, SAID METHOD COMPRISING THE STEPS OF SUCCESSIVELY TRANSMITTING DIFFERENT PARTS OF SAID TOTAL BANDWIDTH SIGNALS WITH EACH SUCH PART CONTAINING AT LEAST SOME SIGNALS DIFFERING IN FREQUENCY FROM THE SIGNALS OF THE OTHER PARTS AND ECH OF SID PARTS HAVING A BANDWIDTH OF LESS THAN ONE OCTAVE, CHANGING THE EFFECTIVE DIMENSIONS OF THE ARRAY BETWEEN THE TRANSMISSIONS OF THE SEVERAL PARTS SO THAT THESE DIMENSIONS AR APPROPRIATE TO THE KNOWN APPARENT VELOCITIES AND THE KNOWN FREQUENCY CONTENT OF THE RESPECTIVE PARTS, RECEIVING EACH PART AT THE TRANSDUCER ARRAY, THE THEN COMBINING THE SIGNALS RECEIVED FROM THE TRANSMISSIONS OF THE SEVERAL PARTS OF YIELD A COMBINED SIGNAL HAVING THE INTENDED TOTAL BANDWIDTH.

Claim 2

A METHOD OF TRANSMITTING AND RECEIVING SIGNALS UTILIZING A TOTAL SIGNAL BANDWIDTH OF MORE THAN ONE HALF OCTAVE AND EMPLOYING A TRANSDUCER ARRAY TO DISCRIMINATE BETWEEN RECEIVED SIGNALS HAVING DIFFERENT APPARENT VELOCITIES ACROSS THE ARRAY, SAID METHOD COMPRISING THE STEPS OF SUCCESSIVELY TRANSMITTING DIFFERENT PARTS OF SAID TOTAL BANDWIDTH SIGNALS WITH EACH SUCH PART CONTAINING AT LEAST SOME SIGNALS DIFFERING IN FREQUENCY FROM THE SIGNALS OF THE OTHER PARTS AND ECH OF SID PARTS HAVING A BANDWIDTH OF LESS THAN ONE OCTAVE, CHANGING THE EFFECTIVE DIMENSIONS OF THE ARRAY BETWEEN THE TRANSMISSIONS OF THE SEVERAL PARTS SO THAT THESE DIMENSIONS AR APPROPRIATE TO THE KNOWN APPARENT VELOCITIES AND THE KNOWN FREQUENCY CONTENT OF THE RESPECTIVE PARTS, RECEIVING EACH PART AT THE TRANSDUCER ARRAY, THE THEN COMBINING THE SIGNALS RECEIVED FROM THE TRANSMISSIONS OF THE SEVERAL PARTS OF YIELD A COMBINED SIGNAL HAVING THE INTENDED TOTAL BANDWIDTH.
