Abstract A new type of microtremor array is presented.Besides the advantages of traditional ones, it is improved by canceling the error item of 6th order Bessel function from space autocorrelation coefficient computed from the sitebetween distance of two groups and thus broadens usable frequency band and to some extents diminishes the influence from disturbance. The principle of design is introduced and effectiveness of the results is validated through simulation and field test.
