Human fall radar Human sensor types, applications and future development

I. Introduction

With the progress of society and the development of science and technology, people have higher and higher requirements for the quality of life, especially for health issues. Human fall radar Human sensor, as a technology that can monitor human movement and health status in real time, has been paid more and more attention. This paper will introduce in detail the types, working principles, application cases and potential in the future development of human fall radar human sensor.

Second, the type of human fall radar human sensor

Human fall radar Human sensor according to the different working principles, can be divided into the following types:

Pulse radar sensor: The echo reflected back by the transmitted pulse signal meets the obstacle is used for detection. This kind of sensor has high precision and resolution, but is susceptible to multipath effects and stray interference.

FMCW radar sensors: Use frequency-modulated continuous wave signals to calculate distance by measuring the frequency difference between the transmitted signal and the reflected signal. With low power consumption and high speed, this sensor is suitable for real-time monitoring and fast response applications.

24GHz radar sensor: operating in the 24GHz microwave frequency band, with a smaller volume and higher moving speed. This sensor is often used for short-range detection, such as vehicle proximity detection, personnel counting, and so on.

Millimeter wave radar sensor: working in the millimeter wave band, with a wide bandwidth and high resolution. This sensor is suitable for the detection and tracking of high-speed moving objects, such as collision avoidance systems in automobiles.

Dual-frequency radar sensor: transmits signals of two different frequencies at the same time, and calculates the distance by comparing the frequency difference between the transmitted signal and the reflected signal. The sensor has good anti-interference ability and high precision, and is suitable for detection in complex environment.

Each of the above types of sensors has its unique characteristics and application scenarios, and the appropriate type can be selected according to actual needs.
