Other AbstractThe study on image theory and the retrieving algorithm of two2dimensional synthetic aperture microwave radiometer with circular antenna array is presented.Based upon simulated annealing algorithm ,we will discuss two solutions of obtaining the ideal thinned array.One solution uses half-circle configuration with very much reduced number of elements and taking an image by rotating the array. The other solution selects element positions around the full circle to provide a roughly uniform coverage in the spatial frequency domain.The results show that both solutions have improved characteristics over the conventional design. For the half2circle case ,if the integration time allows ,with the rotation of the array and the limited time2shared measurements the number of elements can be further reduced to a great extent. For the full2circle case ,the array can be thinned up to the least redundant number ,which can never be reached by the most popular Y shaped array configuration under same spatial frequency coverage constraint.
