Study On Beam Form Synthesis Of Conformal Phased Array

In this thesis, the research of beam form synthesis of conformal phased array is described. Two novel optimizations are introduced,using MATLAB to program and optimize some key parameters of conformal phased array,and the beam form is satisfying.First, the principle of Particle Swarm Optimization (PSO) and Genetic Algorithms (GAs) are investigated. Two kinds of familiar arrays are calculated,the results are as good as reference literature ,the arithmetic are correct .Comparing with GA ,PSO is better.Second, apply PSO to calculate many arrays and get the required scheme according to a project.Theoretically,a column conformal array with small size and few elements to generate a shaped beam with low side lobe and main beam with fixed width and flat top is carried out.Finally, the theory of microstrip power divider is discussed. The equal and 2:1 unequal double-way power divider are simulated and the equal one is produced. The test date is good ,wide bandwidth, small return loss, small insertion loss and excellent isolation, are obtained.
