摘　　要："自导系统"是一门综合性的专业课程,涵盖了数字信号处理和阵列信号处理等方面的内容。本文通过对离散傅立叶变换和波束形成的类比分析,对比了时间采样信号的频域分辨力和空间采样信号的空间分辨力,并设计了计算机仿真实验进行分析对比。教学实践证明,通过课程内容的延展对比,基本理论与实际工程研究的结合,提高了学生的学习动力,教学效果显著。Self-Guide System,containing digital signal processing and array signal processing and other contents,is a comprehensive specialized course.Discrete Fourier transform and beamforming are analyzed,and the frequency resolution and the direction resolution are compared in the paper.For improving teaching effects,two simulation experiments are designed.The teaching practices indicate that the students′ learning interest have been stimulated and their learning motivation have been improved by the instructional design,in which the course contents are extended and compared and the theoretical contents are combined with engineering research contents.

关 键 词：自导 频率分辨力 方向分辨力
