A new method of orthogonal poly-phase code design is proposed to improve signal orthogonality and Doppler tolerance for MIMO radar system. First, eight-phase code which has a better compromise of freedom and processing complexity is generated by Walsh matrix. Initial code sequences are chosen from the constructed codes. Then an adaptive simulated annealing genetic mix algorithm is proposed to numerically optimize orthogonal poly-phase coded signals. Signal orthogonality and Doppler tolerance are taken into account in objective function simultaneously, cross and mutation probability is changed adaptively by optimizing progress. Simulation results show this method can design poly-phase code with lower autocorrelation side-lobe peak and superior Doppler tolerance.
