新一代通用机载雷达信号处理机的实现

Implementation of a new generation of general airborne radar signal processor

为提升机载雷达信号处理机多通道、并行、大运算量的实时处理能力,基于DSP+FPGA结构采用模块化设计构建的新一代雷达信号处理机,符合"通用化、系列化、标准化"的要求,并且根据软件雷达的思想,通过改变算法和软件,使其适应不同的工作环境和任务需要。高性能DSP TS201和大容量FPGA为核心实现的新型通用机载雷达信号处理机的通用平台,主要实现数字脉压、FFT,CFAR,SAR/ISAR等算法。

To improve real-time processing ability of multi-channel,parallel processing and large amount of computing, a new generation of universal airborne radar signal processor is constructed by using modular design which is on the basis of DSP and FPGA.It meets the requirements of generalization,serialization and standardization.Besides,according to the ideas of software radar, it makes the radar adapt to different working environments and tasks required by changing the algorithm and software.The signal processor mentioned in this paper mainly uses high performance DSP TS201 and the high-capacity FPGA to implement the algorithm of digital pulse compression,FFT,CFAR,SAR and ISAR.
