We investigate the methods to optimize the directivity of point source array by using pseudostochastic sequences.Maximum-length sequence(MLS)array and Quadratic-residue sequence(QRS)array are theoretically analysed,and their simulated resposses are shown.The results indicate that pseudostochastic sequences can be used to optimize the directivity of point source array.
