说明： 这个是信号与处理专业的大作业，主要研究两个方面的问题：低通滤波器的阶跃响应特性分析和连续线性系统的求解。通过这次课程设计，将会研究Matlab的一些基本的数值计算应用方法，对计算结果进行形象化地展示，有利于加深对本课程内容的理解。(This is a major task of signal and processing specialty. It mainly studies two aspects: step response characteristic analysis of low-pass filter and solution of continuous linear system. Through this course design, we will study some basic numerical calculation application methods of MATLAB, and visualize the calculation results, which is conducive to deepening the understanding of the course content.)

对地面固定目标设计了一种仅依赖测距传感器的制导律，不再需要传统的视线角信号以及目标和无人机自身的定位信息，再将该制导律推广到对地面匀速和变速移动目标的跟踪制导。相比于现有制导律，本课题提出的制导律结构更为简洁，仅有一个设计参数，并且制导策略更为合理。仿真结果表明所提出的制导律能够实现无人机对地面固定目标的稳定跟踪。(A guidance law that only depends on the ranging sensor is designed for the ground fixed target. The traditional line-of-sight signal and the target and the positioning information of the UAV are no longer needed. The guidance law is extended to the uniform and variable speed moving target Tracking guidance. Compared with the existing guidance law, the guidance law structure proposed by this subject is more concise, with only one design parameter, and the guidance strategy is more reasonable. The simulation results show that the proposed guidance law can achieve stable tracking of UAV fixed targets on the ground.)
