A Novel Spatial Sampling Scheme for DOA Estimation With Movable Arbitrary Sparse Arrays

Sparse arrays have been an important concept in the study of direction of arrival (DOA) estimation since they can obtain the number of degrees of freedom (DOFs) is much larger than that of the number of physical sensors. However, the missing lags in the difference co-array reduce the DOF that is exp...
