| 摘 要： | 针对自适应抗干扰天线研究了复数域的蚁群算法(Ant colony algorithm,ACA),该算法对多极值函数全局寻优具有传统算法不可比拟的良好性能.根据自适应信号处理原理和最小均方误差准则确定ACA所要优化的目标函数,建立了数学模型.为了计算多维复数权值,定义了权值矢量空间,给出了完整的计算步骤.仿真结果表明,该算法适用于自适应抗干扰技术,能够有效抑制多个干扰.通过与其他算法比较,ACA在抑制干扰、保护期望信号方面显示了较好的性能.

| Abstract: | An ant colony algorithm(ACA) for adaptive anti-jam array antenna is studied in the complex number field.ACA has the better capability of finding the global optimum solution than other tradition algorithms.According to the theory of adaptive signal processing and minimal mean square error(MMSE) criterion,the objective function of ACA is found and its mathematical model is established.Then,the space of the weight vector is defined and the steps of ACA are given in order to compute multi-dimensional complex we... |
