摘要
提出了采用快速傅里叶变换(FFT)及快速傅里叶逆变换(IFFT)变换对脉冲压缩CO_2相干激光雷达信号处理,并进行了理论与计算机模拟研究.通过运行所研究的信号处理程序包表明,采用这种方法可以很好地完成信号处理(脉冲压缩)任务,并可准确地提出所需要测量的时间延迟参数.
A method to process signal of a CO2 coherent laser radar by FFT and IFFT pair is presented, and the theoretical and simulation researches are proceeded. The running of the worked out signal processing packet indicates that the signal processing can be completed perferctly, and the time-delay parameter can be extracted precisely by the method.
