利用混合算法优化设计了一种新型单脉冲阵列,此种阵列采用了一种简化的差网络设计,通过合理地划分子阵及选择合适的子阵权,可以较好的解决和差矛盾。在文中的混合算法中,采用了新的粒子群整数算法,新算法通过引入“布朗运动”提高了常规粒子群算法的效率和鲁棒性。文中通过实例及与已有算法的比较表明了其优点。 A new monopulse array is designed and optimized by means of hybrid algorithm. This kind of array uses a simplified network design. By dividing subarrays rationally and selecting proper sub-array right, the contradiction can be well solved. In the hybrid algorithm, a new PSO algorithm is adopted. The new algorithm improves the efficiency and robustness of the PSO by introducing “Brownian motion”. The advantages and disadvantages of the proposed method are compared with the existing ones.
