Single vector sensor output of each channel with different combinations can be used to suppress interferential noise.But the method of higher order power and minimum mean-square error rule include nonlinear calculation and caused target signal distortion.The common linear calculation method can just suppress the interferential noise of fixed direction between target.Weight coefficient are set for single vector sensor output of each channel.In isotropic noise field

the interferential noise of any direction can be suppressed by adjusting the weight coefficient value based on minimum output noise power.Simulations show that if the differences between interferential noise direction and target direction is 70°～290°

the interferential noise can be completely suppressed

SNR of targer signal is not decreased and the signal has no distortion.
