A CIRCUIT ARRANGEMENT FOR PROCESSING DIGITALIZED RADAR PULSE ECHO SEQUENCES WHEREIN TARGETS ARE REPRESENTED BY BLOCKS OF BINARY ONE-DIGITS, WHICH BLOCKS ARE OF DIFFERENT LENGTHS BUT HAVE A MAXIMUM LENGTH OF N DIGITS, AND WHEREIN THE BLOCKS ARE CORRELATED SO AS TO PERTAIN TO TARGETS LOCATED WITHIN PREDETERMINED DISTANCE RINGS, THE COMBINATION WHICH COMPRISES: (A) A SHIFT REGISTER HAVING A CHAIN OF REGISTER ELEMENTS, THERE BEING AT ONE END OF SAID CHAIN AN INPUT FOR RECEIVING THE DIGITALIZED AND CORRELATED BLOCKS; AND (B) A LOGIC CIRCUIT HAVING INPUTS CONNECTED TO THE OUTPUTS OF SAID REGISTER ELEMENTS FOR PRODUCING AN OUTPUT SIGNAL ONLY WHEN THERE APPEARS IN THE MIDDLE OF SAID SHIFT REGISTER CHAIN A BLOCK HAVING A MAXIMUM OF N ONE-DIGITS, OR WHEN THERE IS IN SAID SHIFT REGISTER CHAIN A LARGER BLOCK OF ONE-DIGITS, RESULTING FROM TWO TARGETS, WHOSE CHRONOLOGICALLY FIRST ONE-DIGIT HAS REACHED A GIVEN REFERENCE ELEMENT WHICH IS REMOTE FROM SAID INPUT OF SAID CHAIN OR WHOSE CHRONOLOGICALLY LAST ONE-DIGIT HAS REACHED A GIVEN REFERENCE ELEMENT WHICH IS NEAR SAID INPUT, WHEREBY THE TARGET MIDPOINTS ARE DETERMINED.
