Jd. Sahr et Er. Grannan, SIMULATED ANNEALING SEARCHES FOR LONG BINARY PHASE CODES WITH APPLICATION TO RADAR REMOTE-SENSING, Radio science, 28(6), 1993, pp. 1053-1055
We apply the technique of simulated annealing to search for long discr
ete codes with special autocorrelation and ambiguity function properti
es, suitable for radar applications. This technique provides access to
codes which are far too long for exhaustive search, and to codes whos
e correlation properties do not lend themselves to algebraic investiga
tion. We illustrate the process with two new kinds of binary phase cod
es.
