Design of radar orthogonal signal based on genetic algorithm and simulated algorithm

To resolve the design of radar orthogonal signal problem,this paper proposed a new algorithm based on genetic algorithm and simulated algorithm.The algorithm used genetic algorithm for global search, while simulated algorithm for local search.It improved genetic algorithm strategy, and introduced the adaptive probability changes to the crossover and mutation, and adaptive to preserve the best individual, and the genetic algorithm results were selectively simulated operation, which resolved the problem of premature and time. The experiment results show that the proposed algorithm is effective and feasible, which the performance is better than traditional genetic algorithm and simulated algorithm.
