The algorithm takes into account of the characteristic of patterns of array’s elements and can control sidelobe lovels arbitrarily and overcome the drawbacks of traditional techniques.

The mainlobe shaping,sidelobe levels and null can be controlled efficiently.

in order to combine and optimize the current distribution,which makes the maximum sidelobe level of this uniform linear array as low as possible,and compares the optimization effect of different operator combination,gets some applicable conclusion.

Under the optimization constraints of the number of element,the aperture and the minimum element spacing,the MGA has been utilized to reduce the peak sidelobe level(PSLL) of the array.

Due to the effect of feeding error on antenna’s radiation performances, which causes the degradation of the sidelobe level , the pointing accuracy and the anti-jamming capability of phased arrays.

Through the theoretical analysis and computer simulation,the statistical peak sidelobe level(PSL) of compression wave of the correlation receiver,and the resolved ability were studied.

In this paper,the basic principle about the mean sidelobe level and the peak sidelobe level are described.

The determination of radar antenna sidelobe level has qualitative principles,but have no distinct quantitative analytic formulas,so it is more or less indistinctness that the specification of sidelobe level is put by users or designers.
