Optical orthogonal codes and multi-target Costas and sonar arrays

We explore the interconnection between Costas and Sonar arrays for multiple targets and optical orthogonal codes. Also we obtain a family of multiple target double periodical arrays (more than one array) whose auto- and cross-correlation is one and a family with auto-correlation 2 and cross-correlation 1. Furthermore we give a method to obtain optical orthogonal codes from multiple target arrays.
