Abstract :
The design of large thinned phased array antenna and its sidelobe level are studied. Computations are made for 3 aperture sizes, 30 reference aperture amplitude distributions and 9 thinned rates with random number of long period. 45000 arrangements of elements over thinned apertures and their 3D patterns in full space are calculated. Some useful results are derived. Finally, the mathematical regression method is used to obtain the formula for estimating the sidelobe level with high accuracy
