Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
100 words
A SYSTEM FOR CORRELATING SIGNALS RELATING TO TWO PARAMETERS OF INFORMATION, A COMPRISINGG A TWO-DIMENSIONAL ELECTRO-OPTICAL SONIC DELAY LINE CORRELATOR FOR CORRELATING AT LEAST TWO SIGNALS ALONG ONE DIMENSIONAL AXIS OF SAID CORRELATOR, AND A TWO-DIMENSIONAL ELECTRO-OPTICAL SONIC DELAY LINE MEANS FOR CORRELATING A THIRD SIGNAL WITH THE FIRST-MENTIONED SIGNALS, THE TWO DIMENSIONAL AXES OF SAID DELAY LINE MEANS BEING ORIENTED AT AN ANGLE OTHER THAN 0* OR 90* RELATIVE TO THE CORRESPONDING AXES OF SAID CORRELATOR, WHEREBY A SIGNAL ON SAID DELAY LINE MEANS IS PROVIDED WITH A COMPONENT CORRESPONDING TO EACH OF THE TWO DIMENSIONS OF SAID CORRELATOR.
Claim 2
Independent Claim

Claim 3
Independent Claim
39 words
A SYSTEM AS SET FORTH IN CLAIM, 1, WHEREIN SAID TWO SIGNALS ARE DERIVED FROM A RADAR ECHO SIGNAL RECEIVED AT TWO SPACED ANTENNAE, AND SAID THIRD SIGNAL IS DERIVED FROM THE TRANSMITTED RADAR SIGNAL OF SAID ECHO SIGNAL.
Claim 4
Independent Claim
69 words
A METHOD OF DETERMINING THE TIME DELAYS BETWEEN THREE SIGNALS HAVING SUBSTANTIALLY SIMILAR WAVEFORMS, WHEREIN SAID SIGNALS HAVING KNOWN RATIOS OF TIME DELAY THEREBETWEEN, COMPRISING EFFECTIVELY TIME DELAYING SAID SIGNALS RELATIVE TO ONE ANOTHER IN ACCORDANCE WITH SAID RATIOS, CORRELATING THE RESULTANT SIGNALS, AND DETECTING THE RELATION OF MAXIMUM CORRELATION BETWEEN ALL SAID SIGNALS RELATIVE TO A REFERENCE SCALE AS A MEASURE OF ACTUAL TIME DELAY BETWEEN SAID SIGNALS.
