1. A multiple input, multiple output (MIMO) antenna frame array for use in a radar system, comprising:
a first plurality of elements arranged in a first column and a second column, said second column spaced a first distance from said first column;
a second plurality of elements arranged in a first row and a second row, said second row spaced a second distance from said first row;
wherein said first column and second column are skewed vertically along their major axes in accordance with a first skew factor;
wherein said first row and said second row are skewed horizontally along their major axes in accordance with a second skew factor; and
wherein said first skew factor and said second skew factor are both greater than λ/2 where λ is the wavelength of the transmitted radar pulse.
