UWB technology is a technology that uses short pulse signals for communication and ranging, and its signal bandwidth is usually more than 500MHz, and even up to several GHz. This wide band feature makes UWB radar far superior to traditional radar technology in terms of time resolution and distance measurement accuracy, and can achieve centimeter-level positioning accuracy, which is very suitable for scenarios requiring high-precision positioning, such as automatic following cars, indoor navigation, and obstacle avoidance of drones.

1.1UWB radar chip: Core driving force

As the "heart" of the whole system, UWB radar chip integrates several functional modules such as signal generation, reception and processing. The advanced UWB radar chip is designed with low power consumption, which can extend the battery life of the device while ensuring high precision positioning. In addition, the highly integrated chip design also reduces the complexity and cost of the system, and promotes the popularization of UWB technology.

1.2UWB antenna: antenna for accurate perception

As an important part of radar system, UWB antenna is responsible for receiving and transmitting UWB signals. In order to match the high frequency characteristics of UWB signals, UWB antennas are usually specially designed, such as microstrip antennas, Vivaldi antennas, etc., to ensure efficient transmission and reception of signals. The performance of the antenna directly affects the positioning accuracy and stability of the system, so it is very important to choose the appropriate UWB antenna in the design of automatic following car.

1.3UWB module: Integration and easy deployment

The UWB module is to package the UWB radar chip and antenna, the necessary circuit components and software algorithms into an independent unit, which is convenient for users to quickly integrate into various devices.
