基于FPGA的分布式协同雷达数字脉压系统设计与实现
|
摘要
利用某一雷达作为外辐射源,借助双(多)基地雷达收发分置的体制优势,通过多站分布协同,实现对一定范围区域的有效监测。在此工作背景下,为了能在接收机处有效地检测微弱目标,作为匹配滤波和相关接收理论的实际应用,脉冲压缩在信号处理中发挥着重要作用。借助现场可编程逻辑器件(FPGA)可在脉冲压缩环节实现信号高速处理,考虑实现过程中回波信号的特征,选择合适的压缩算法,同时综合FPGA硬件电路的设计特点,对脉压环节进行优化,便于后续的检测设计和功能拓展。
In order to make use of the advantages of dual( multi) base radar receiving and dispatching system,using a radar as an external radiation source,achieves a certain range of areas of effective monitoring through the distribution of multi-station coordination. In this background,pulse compression plays an important role in signal processing in order to effectively detect weak targets at the receiver,as a practical application of matched filtering and correlation reception theory.The Field-Programmable Gate Array can realize high-speed signal processing in pulse compression.Considering the characteristics of echo signal in the process and selecting the appropriate compression algorithm,we can then integrate the design features of FPGA hardware circuit and optimize the pulse-compression to follow-up testing design and functional expansion.
