摘　　要：复杂信号侦察处理是多功能数字阵列雷达(MFDAR)的重要组成部分,可以服务于MFDAR的雷达与通信信号侦察以及电子战等多种用途,其中信号侦察的实时性与功能的灵活适应性是MFDAR的关键。在详细研究MFDAR信号侦察处理特点基础上,提出了两阶段可配置的信号处理流程,构建了基于混合结构的宽带信号侦察可配置计算模型BSRRCM。BSRRCM对"非确定、非单向"的信号流进行了描述,利用"固化典型流程、设置有限配置点"的思想,BSRRCM将应用分解成可完全重配置的典型处理流程和可局部重配置的功能任务序列,快速映射到合适的计算平台上,在确保信号处理实时性前提下使系统获得了动态的灵活配置能力与可扩展性。Reconnaissance of complex signal is an important part of the multifunctional digital array radar（MFDAR）,which serves for multipurpose,including radar communication signal reconnaissance or ESM（electronic support measurement）.The real-time responsivity and flexibility are crucial for such a reconnaissance system.In this paper,we proposed a two-stage reconfigurable signal processing according to the reconnaissance characteristics of MFDAR.Then we constructed the Broadband Signal Reconnaissance Reconfigurable Computing Model（BSRRCM） based on the hybrid reconfigurable architecture to implement the processing procedures.BSRRCM describes non-identified and not unidirectional signal flow.Taking BSRRCM,we can decompose an application into a particular procedure which can be reconfigured completely and a partial reconfiguration tasks sequence,then this reconfigurable procedure and tasks sequence could be mapped on the appropriate computing platform.The BSRRCM has many merits at the same time,including flexibility,dynamic reconfigurability,multipurpose and scalability.
