Simulated annealing searches for long binary phase codes with application to radar remote sensing

摘要

We apply the technique of simulated annealing to search for long discrete codes with special autocorrelation and ambiguity function properties, suitable for radar applications. This technique provides access to codes which are far too long for exhaustive search, and to codes whose correlation properties do not lend themselves to algebraic investigation. We illustrate the process with two new kinds of binary phase codes.
