A new optimum method of shared aperture pattern synthesis is proposed based on the new global optimization algorithm,Wind Driven Optimization( WDO),for the shared aperture array antenna. Firstly,the space constraint condition of the array element adjacent to two arrays is designed,and the Peak Side Lobe Level( PSLL) of the two sub-array patterns is used as the objective function. Then,according to the constraint formula,the initial coordinates of sub-array 1 and sub-array 2 array elements are developed successively.These two sub-array elements positions are optimized by using the WDO method to reduce PSLL of the pattern synthesis,in order to fulfill the design of shared aperture antenna array working at different frequencies.Finally,a simulation is made and the result shows that: compared with the particle swarm optimization algorithm and the traditional SMI algorithm,this proposed algorithm has better feasibility and effectiveness in the shared aperture pattern synthesis.
