As we all know, the traditional radar technology is widely used, such as airborne, shipboard, base radar and other aspects to detect and image targets. In daily life, we can use radar sensors to achieve weather forecast, traffic control, resource exploration and many other applications.

In recent years, with the rapid development of semiconductor technology, the size and power consumption of many radars are greatly reduced. With the use of millimeter wave, ultra wideband technology and multi transmitter and multi receiver, combined with innovative signal processing technology and chip with increasing computing power, radar's sensing function is becoming more and more powerful.

What technology is radar sensing?

The so-called radar sensing is a kind of wireless sensing technology. By analyzing the echo characteristics of the received target, the position, shape, motion characteristics and trajectory of the target are extracted and found, and the characteristics of the target and environment can be further inferred. Its function is similar to that of human eyes and ears.

Compared with other sensors, radar sensing has many unique advantages. For example, compared with visual sensors, radar is not affected by light and shade, and has the ability to penetrate obstacles, which can better protect personal privacy; compared with ultrasonic technology, radar can perceive a longer distance, and will not cause harm to people and animals.

Radar sensing can support very rich application scenarios. For example, millimeter wave radar has been widely used in the field of automobile assisted driving, to detect pedestrians and vehicles in front, and to achieve collision avoidance warning. In addition, as shown in the figure above, radar has many potential applications in the fields of home, intelligent building, automatic driving and wearable devices. With the continuous development of new low-power, small radar sensors, radar technology has been widely used in many intelligent devices and electronic products
