摘要
通过距离时域脉冲相干法、距离频域脉冲相干法以及二维频域快速傅氏变换法等三种回波信号生成方法生成回波,并通过计算量估计和空间估计对其进行分析和研究,最后对其性能做出比较。
Time domain pulse coherence method the distanee from the frequency domain pulse coherence method and the two-dimensional fast Fourier transform frequency domain methods such as signal generation method to generate three echo echo, and is estimated by calculating the amount of space and its estimated and research, and finally to ,,lake a comparison of their performance.
