Minimum redundancy linear arrays (MRLA) are widely used in radio astronomy,microwave radiometry,radar and other fields.Based on the Fourier properties of arrays with optimal co-array properties,the co-array properties of MRLAs with minimum sidelobe level are presented for the first time,validated by simulations of different MRLAs with 5~9 elements.The upper bound of the peak sidelobe level (PSL) of a MRLA is also derived.
