Method and apparatus for recording of radar signals

Claim 1

A SYSTEM FOR RECORDING BOTH THE PHASE AND AMPLITUDE OF RADAR SIGNALS REFLECTED FROM REMOTE TARGETS, SAID SIGNALS BEING IN THE FORM OF REPETITIVE RANDOMLY SPACED HIGH FREQUENCY ALTERNATING WAVE PULSES, COMPRISING MEANS FOR WRITING THE RADAR SIGNALS FROM A SINGLE TRANSMITTED PULSE UPON A FIRST SEGMENT OF A STORAGE SURFACE, ONE DIMENSION OF SAID SEGMENT CORRESPONDING TO TARGET RANGE AND A SECOND ORTHOGONAL DIMENSION OF SAID SEGMENT CORRESPONDING TO THE TIME OF OCCURRENCE OF SUCCESSIVE PULSES, SAID MEANS INCLUDING A CONTROL MEANS FOR WRITING THE ALTERNATING COMPONENT OF EACH TARGET PULSE ALONG SAID SECOND DIMENSION AT ITS RESPECTIVE RANGE COORDINATE, MEANS FOR POSITIONING THE RADAR SIGNALS DERIVED FROM SUCCEEDING TRANSMITTED PULSES UPON CORRESPONDING ADJACENT SURFACE SEGMENTS SO THAT THE ALTERNATING COMPONENTS OF SUCCESSIVE RADAR SIGNALS REFLECTED FROM SINGLE TARGETS ARE RECORDED IN APPROXIMATE ALIGNMENT ALONG THE SECOND DIMENSION OF ADJACENT SEGMENTS AT THEIR RESPECTIVE TARGET RANGE COORDINATES, WHEREBY THE RECORDED SIGNALS MAY BE READILY READ OUT SO AS TO PROVIDE AN INDICATION OF THE DOPPLER FREQUENCY SHIFT OF SAID REFLECTED RADAR SIGNALS BY UTILIZING THE PHASE RELATIONSHIP BETWEEN ALIGNED SUCCESSIVE RECORDED PULSES.

Claim 2

A SYSTEM FOR RECORDING BOTH THE PHASE AND AMPLITUDE OF RADAR SIGNALS REFLECTED FROM REMOTE TARGETS, SAID SIGNALS BEING IN THE FORM OF REPETITIVE RANDOMLY SPACED HIGH FREQUENCY ALTERNATING WAVE PULSES, COMPRISING MEANS FOR WRITING THE RADAR SIGNALS FROM A SINGLE TRANSMITTED PULSE UPON A FIRST SEGMENT OF A STORAGE SURFACE, ONE DIMENSION OF SAID SEGMENT CORRESPONDING TO TARGET RANGE AND A SECOND ORTHOGONAL DIMENSION OF SAID SEGMENT CORRESPONDING TO THE TIME OF OCCURRENCE OF SUCCESSIVE PULSES, SAID MEANS INCLUDING A CONTROL MEANS FOR WRITING THE ALTERNATING COMPONENT OF EACH TARGET PULSE ALONG SAID SECOND DIMENSION AT ITS RESPECTIVE RANGE COORDINATE, MEANS FOR POSITIONING THE RADAR SIGNALS DERIVED FROM SUCCEEDING TRANSMITTED PULSES UPON CORRESPONDING ADJACENT SURFACE SEGMENTS SO THAT THE ALTERNATING COMPONENTS OF SUCCESSIVE RADAR SIGNALS REFLECTED FROM SINGLE TARGETS ARE RECORDED IN APPROXIMATE ALIGNMENT ALONG THE SECOND DIMENSION OF ADJACENT SEGMENTS AT THEIR RESPECTIVE TARGET RANGE COORDINATES, WHEREBY THE RECORDED SIGNALS MAY BE READILY READ OUT SO AS TO PROVIDE AN INDICATION OF THE DOPPLER FREQUENCY SHIFT OF SAID REFLECTED RADAR SIGNALS BY UTILIZING THE PHASE RELATIONSHIP BETWEEN ALIGNED SUCCESSIVE RECORDED PULSES.
