Abstract

The angle measurement experiment is an innovative experiment in the digital signal processing course. This experiment combines engineering practice to allow students to comprehensively master the basic knowledge of circular convolution and window function. Aiming at the problems of the traditional amplitude ratio monopulse angle measurement method, due to the coupling of the azimuth angle and the pitch angle, the normalized error curve is not unique and the angle measurement results are uncertain. In this paper, a new monopulse angle measurement method based on sinusoidal coordinate system is designed. Through the transformation of the sinusoidal coordinate system, the coupling of the azimuth angle and the pitch angle in the angle measurement process is solved, thus realizing the uniqueness of the angle measurement result. On the premise of paying attention to the foundation, professionalism and practicability, this paper introduces innovative experimental methods and updates the teaching content. Through this experiment, students' innovative thinking and problem-solving ability are cultivated.

数字信号处理课程角度测量方法实验教学改革

角度测量实验是数字信号处理课程中的一个创新实验。本实验结合工程实践，使学生全面掌握圆卷积和窗函数的基本知识。针对传统幅度比单脉冲测角方法存在的问题，由于方位角和俯仰角的耦合，归一化误差曲线不唯一，测角结果不确定。本文设计了一种基于正弦坐标系的单脉冲角度测量方法。通过正弦坐标系的变换，解决了角度测量过程中方位角和俯仰角的耦合问题，从而实现了角度测量结果的唯一性。在注重基础、专业、实用的前提下，创新实验方法，更新教学内容。通过这个实验，培养学生的创新思维和解决问题的能力。
