A practical anti-aliasing starlike array in 2D aperture synthesis microwave radiometer

There is no alias-free FOV when the least space is more than 3.07 wavelength because of bigger receiver size in 8mm aperture synthesis microwave radiometers. Background cancellation method which can eliminate aliasing in removable object's imaging is no useful when the scene cannot move. This paper give a new starlike array whose visibility samples is half of receiver size, so there is no severity aliasing problem in the new starlike array. The result of the emulate experiment show the imaging quality of starlike array is more higher than the quality of Y array.
