Abstract
The notion of poly-alphabetic radar, which gave improved performance through coincidence detection, is analyzed. It is argued that what was central to it was a poly-semanticism which was achieved through poly-alphabetism. But the former can be achieved even within a single alphabet. This is illustrated and the attendant signal design problem is solved. The design is completed in two steps, first one using restricted Hamming scan for interspersed sequences and the second one using a complete Hamming scan using an appropriate joint objective function.
