该算法既保留了遗传算法的搜索特性,又利用了免疫算法的多机制求解多目标函数最优解的自适应特性,在很大程度上避免了“早熟”,收敛于局部极值。
生物体的免疫系统是一个高度进化、复杂的系统,它能自适应地识别和排除入侵肌体的抗原性异物,保护机体免受损害及维持内坏境稳定,并具有学习、记忆和自适应调节的能力。当抗原入侵时,免疫系统通过自体耐受对‘自己’和‘非己’进行识别,并产生最恰当的抗体排除抗原,通过抗体与抗体之间、抗原与抗体之间的相互刺激和抑制关系,降低抗原对免疫细胞的刺激,抑制抗体的过度分化、增殖,保证免疫平衡并维持抗体的多样性。同时在免疫过程中将产生抗体的部分细胞作为记忆细胞保存下来,对于今后侵入的同类抗原,相应的记忆细胞受到激发而产生大量的抗体。为提高生物体的免疫机能,医学上往往根据抗原性异物提取疫苗给生物体接种,接种过的生物体由于免疫细胞预先获得了抗原染色体的特征信息,因而在类似抗原入侵时,能迅速产生亲和度很高的抗体,有效抵御入侵。(The search algorithm only retains the characteristics of genetic algorithms, and use multiple mechanisms of immune algorithm for solving multi-objective characteristics of adaptive optimal solutions, in large part to avoid the " premature" , converge to local minima. Organism' s immune system is a highly evolved, complex system which adaptively identify and remove foreign matter intrusion antigenic body, protecting the body injury and maintain internal stability bad environment, and has learning, memory and adaptive Ability. When the antigen invasion of immune system tolerance to autologous ' own' and ' non-self' to identify and produce the most appropriate antigen antibody excluded by between antibody and antibody, antigen and antibody mutual stimulation and inhibition of the relationship between reduce the antigen to stimulate immune cells, antibodies inhibit excessive differentiation, proliferation, immune balance and ensure the maintenance of antibody dive)

说明: 浅层海洋环境由信源组成声源,海洋形成信道,和水听器阵列组成接收器。在这个传播模型中,信源,信道和接收信号这三者,通常能知二求一,具体应用诸如利用海洋环境参数和接收到的信号来定位声源,或者通过计算发射信号和接收信号之间的差异,反演海洋环境参数。
而在接收器方面,我们通过设置各向同性的水听器阵列。通过算法和处理器,我们便能量化模型,传统是处理器主要基于接收信号是高斯信号,而海洋中存在着大量的有色噪声。本课题的研究目的便是在前人的基础上,在海洋声层析成像的背景下,在信源与接收器阵列之间,引入信号的高阶统计量,对非高斯过程的水下信号源进行定位,并提高算法的性能和准确性。
利用非高斯过程的高阶累积量不恒为零的特点,滤去高斯有色噪声对信号的影响,其又包含了信号的相位信息,便可以极大的优化匹配场处理过程的性能和准确性。(After receiving signals based on high order cumulant matched field processor after matched field localization, the positioning effect will be more accurate, sidelobe suppression more effectively, and compared with other traditional matched field processor in low SNR environment, it can position more accurately.)
