2.1 Sensor and perception technology

Before discussing the principle of radar body sensing switch, let's first understand the concept of sensors and sensing technology.

A sensor is a device that can sense and measure a certain physical quantity or environmental information. It can convert perceived physical quantities or environmental information into usable electrical signals or other forms of signals for processing, transmission and control.

Sensing technology refers to the technical means of collecting and processing environmental information by using sensors. Through perception technology, we can obtain all kinds of information in the environment in real time, and make corresponding responses and decisions based on this information.

2.2 Principle and application of radar

Radar is a technology that uses electromagnetic waves for detection and ranging. It uses the characteristics of electromagnetic wave propagation in space to detect and locate the target by transmitting and receiving electromagnetic wave.

Radar is mainly composed of transmitter, receiver, signal processor and display. The transmitter emits high-frequency electromagnetic waves, which are scattered and reflected when they meet the target. The receiver receives scattered and reflected electromagnetic waves and converts them into electrical signals. The signal processor processes and analyzes the received signal and extracts the target information from it. Display the result as an image or other form through the display.

In addition to being widely used in the military field, radar technology is also widely used in the civilian field, such as weather radar, navigation radar, traffic monitoring radar and so on.
