Detailed explanation of the composition and principle of FMCW radar

Engineering men ultimately want to convert technology into products. This concept should be instilled in the classroom of the university, otherwise they always feel that endorsement is very useful, and they are like a liberal arts student. Most of the students trained in our college are the liberal arts students' learning methods, back topics, and answers. If you change the parameters a little, you won't be doing a problem!

Do not talk about this topic, return to the theme! Explain the composition and principle of the FMCW radar.

FMCW, that is, frequency modulated continuous wave. FMCW technology and pulse radar technology are two techniques used in high precision radar ranging. The basic principle is that the transmitted wave is a high-frequency continuous wave, and its frequency changes with time according to the triangular wave law.

FMCW (Frequency Modulated Continuous Wave), the frequency of the received echo is the same as the frequency of the transmitted frequency. It is a triangular wave law, but there is a time difference. The target time can be calculated by using this small time difference.

Because of its advantages of no distance blind zone, high resolution and low transmission power, it has received widespread attention in recent years.
