摘要
针对日益增强的小卫星平台搭载电子侦察载荷的需求,提出一种应用于宽频率范围的通信侦察信号处理方案,在一片集成度较低的FPGA中完成信号数字下变频、频谱分析、数据存储和传输等复杂功能。通过在FPGA中进行滤波器、存储器复用等办法,充分利用现有FPGA的资源,减少器件数量,实现了平台对载荷小型化、低功耗、功能全、效率高的要求。试验结果验证了该设计的实用性。
Al^traet： According to the growing demand of moonlet-based electronic reconnaissance equipment, a signal pro- cessing design scheme for wide frequency range communication reconnaissance is proposed in which the complex functions such as signals digital down conversion, spectrum analysis, data storage and transfer are realized in a low density FPGA（Field-Programmable Gate Array）. Filters and memories are used repeatedly in the FPGA to take full advantage of resources and reduce the number of components, so that miniaturization, low power consumption, full functions, high efficiency for moonlet-based equipment are achieved. The feasibility of the scheme is verified by test. Key words： moonlet-based communiation reconnaissance; signal processing; filter bank; digital down conversion
