本文针对复杂、密集、顺序信号处理系统的重构问题，提出了一种多级可重构信号处理流程（MSRSPF）。将信号处理流程划分为若干阶段，并通过统一的接口进行连接。通过分阶段处理流程的结合，整个系统可以在多种功能的模式下工作，并根据应用需求的变化快速切换到更适合的模式。作为一个应用实例，介绍了MSRSPF在无源信号侦察中的应用。基于MSRSPF的侦察系统具有灵活性和对电磁环境的适应性，能够从不同角度获取电子信息，可靠性更高。性能测试结果表明，MSRSPF支持多种硬件逻辑，具有良好的可重构性，时间开销不超过几秒。
In this paper, we focus on the reconfiguration of complex, intensive and sequential signal processing systems and propose a Multi-Stage Reconfigurable Signal Processing Flow (MSRSPF). The signal processing flow is partitioned into a number of stages which are connected with unified interfaces. With the combination of staged processing flow, the whole system can work at multiple modes with diverse functions and switch to a more suitable mode quickly according to the change of application requirements.As an application case, we introduce the usage of MSRSPF in passive signal reconnaissance. The reconnaissance system based on MSRSPF is flexible and adaptable to the electromagnetic environment, and can get the electronic information from different views with more reliability. The performance testing results show that MSRSPF supports multiple hardware logic and has a good reconfigurability with time overhead no more than a few seconds.
