摘　　要：在分析声呐信号处理特点的基础上,提出一种称为级联阵列机的多处理器体系结构,用以实现大型数字式声呐系统。并对该体系结构中的各种要素,包括总线协议,数据传输,基本处理单元进行了详细讨论,最后给出一个使用级联阵列机结构实现数字声响系统的设计步骤。From the analysis of the characteristics of sonar signal processing, a new achitec-ture called cascade link achitecture to implement large digital sonar system with general processors and special signal processors is proposed. This achitecture is very suitable for large mult-chanel sonar signal processing. The basic elements, including data bus protocal, data transmition, control unit, basic processing cell are discussed. Last, a regular step to design a digital sonar using this achitecture are suggested.
