| dc.description.abstract | This paper uses the Ultrasound FMCW radar provided by Tongzhi Electronics for short-distance measurement of objects. Hardware equipment, chips and data will be mentioned in the content, and then collected in the way of NeighCoef. This paper is divided into five parts in total.
The first part of this thesis will give a basic description, introduce the background of the research, research motivation and the outline of the thesis, the second part will introduce the FMCW chirp system, including system introduction, signal simulation, radar introduction and how the FMCW system measures distance, This chapter has related introductions. The third part introduces what NeighCoef is, the theoretical background of this method and how this method processes the signal to achieve the purpose of reducing noise. In this chapter, there will be a complete formula description, and the fourth part will simulate As well as comparing the difference before and after the signal, various distance data will be attached, from 90cm to 150cm every 30cm is an interval, the fifth part will make a summary, which includes a discussion of the simulation results and what problems still need to be overcome in the future and Where else can we dig deeper. | en_US |
