Cross Entropy (CE) has been recently applied to combinatorial optimization problems with promising results. In this short paper a CE based algorithm is presented to search for binary sequences with good aperiodic autocorrelation properties. The algorithm proposed can explore and exploit the solution space efficiently. In most cases, it can frequently find out binary sequences with higher merit factor and lower peak sidelobe level very quickly.
