[Abstract]:Distance is the length between two points in space. Ranging is the most basic part of our daily life and work Ren Wuzhi. Since ancient times, diligent and intelligent people have begun to explore. So far, we have the measurement units of distance "ruler", "inch", "li" and international unit "kilometer", "meter", "centimeter" and so on. At the same time, due to the limitations of technology and times. In the process of exploration, the methods of "pointing and measuring the river", "taper", etc. With the progress of science and technology and the times, urban development and construction are accelerated. In the age of information, high speed and intelligence. Distance measurement has become one of the indispensable techniques of terrain. Engineering measurement all need certain ranging means. But now people have mastered the effective ranging methods for various situations, mainly: ultrasonic ranging sensor, laser ranging sensor, radar ranging sensor. Infrared ranging sensor. Based on the physics principle, this topic deduces the ranging formula and designs the overall experimental frame. The first two chapters of the paper introduce the modern ranging technology and various sensors. The background of microwave ranging is introduced and the formula of ranging is deduced. In chapter 3, the experimental framework is designed, and the formula derived in chapter 2 is verified. The static single target is measured by moving probe. The formula of Doppler ranging is verified. Based on the frequency acquisition and display of single chip, the Doppler microwave ranging method is realized, and a new ranging device is developed, which is simple in structure and easy to operate. The sensor is sensitive, responsive and sensitive to temperature, noise, weather and humidity.
