摘要
为实现线性调频信号的数字脉冲压缩,设计一个FPGA硬件平台,并着重提出一种基于FPGA IP核的脉冲压缩设计方法。针对脉冲压缩进行了理论分析和Matlab仿真,设计完成后对系统软、硬件进行了全面测试,并根据实测数据对脉冲压缩结果进行了分析。结果表明,该系统可实现1 024点的脉冲压缩功能,主副瓣比、主瓣宽度等指标与理论仿真结果一致。该方法的参数设置灵活,可以简化软件设计,缩短研发周期。
A hardware platform based on the field programmable gate array （FPGA） was designed to implement the digital pulse compression of LFM （Line Frequency Modulation） signal. The design method of pulse compression based on FPGA IP core is proposed in this thesis. The theoretical analysis and MATLAB simulation are performed for pulse compression. With the accomplishment of designs, a comprehensive evaluation test on system software and hardware was conducted, as well as analysis on result of pulse compression based real-time experimental data. The result shows that the system is capable to perform 102d-points pulse compression. The indexes of the amplitude ratio of main lobe to side lobe and mail lobe width are consistent with the result of theoretical simulation. The design method can conduct parameter setting flexibly, simplify software design and shorten the period of research and development.
