During World War II, the Allies used radar technology to successfully intercept the Nazi bombing of London and accurately locate the Royal Navy. It can be said that radar technology reversed the situation of the Allied and Nazi World War II.

Today, radar sensors have entered the lives of ordinary people, including autonomous vehicles, game consoles and other consumer electronics. A list of common cases will be given in the afternoon:
Autopilot: In 2007, GM and Carnegie Mellon University's Tarton Racing team used small radar sensors to develop autonomous vehicles and win the DARPA City Challenge. Radar sensors are undoubtedly one of the most important technologies in autonomous vehicles and drones.
Game consoles: Today, researchers at the Massachusetts Institute of Technology in the United States have applied radar sensors to game consoles to identify user gestures.
Internet of Things: Fybr USA uses small radar sensors for parking space detection to create the most accurate parking lot detection system. Fybr's products integrate both radar and geomagnetic detection technologies. This unique dual-mode sensor greatly improves the accuracy and stability of the product.
Automotive Electronics: Small radar sensors have been widely used in automatic cruise systems, blind spot detection systems, and parking assist systems in advanced vehicles. Radar sensors play a vital role in these systems, which protect passenger safety.
Dr. Gregory Charvat of the Massachusetts Institute of Technology's Lincoln Laboratory pointed out that previous radar technology was mainly used in government and military fields because the cost of radar devices was too high. Now, there are already radar sensors on the market that cost less than $10.
The picture above shows the radar sensor K-LC1A from Swiss RFbeam, which Dr. Gregory Charvat used in the course. Dr. Gregory Charvat said that the sensor's volume price is less than $10, which greatly reduces the threshold for students to use radar sensors. He recommends that students use the sensor for DIY experiments.
Gregory Charvat's radar sensor course is very popular at MIT. To this end, he exposes the courseware to the MIT Open Class website, and interested friends can download and learn.
Dr. Gregory Charvat admits that the market application of small radar sensors has just begun and has a very broad future.
