Optical orthogonal pulse compression codes by hopping
Abstract
The letter describes a simple digital processing technique for using standard M sequences or quadratic residue codes in such a way that their optical correlation is truly orthogonal. This finds important application in optical radar applications where near stationary targets are involved.
