Today, sensors are the most widely used to make intelligent decisions and ensure a safe, efficient environment in every sector. One of these sensor types is millimeter-wave Radar (mmWave Radar module), a sensor often used in sectors like automotive, industrial, civil, and meteorological. Millimeter wave radar works in millimeter waves and refers to the frequency domain of 30–300 GHz (the wavelength is 1–10 mm). Millimeter-wave radar is often useful to sense velocity and angle accurately without interruption.


What is mmWave Radar and Why Do You Need It?

A millimeter-wave radar basically consists of a radio-frequency transmitter or other receiver components. These components help to implement mmWave radar technology for new advancements in the transmit-receive system. In these advanced systems, millimeter-wave Radar is for accurate location and velocity with no obstruction. Moreover, it helps to get better antenna miniaturization via centimeter waves.

 

 In various applications, using the MmWare Radar module is often a better use of technology and makes development easier. You can use it to locate clouds in meteorological sectors. When implementing, you should choose the type of mmWare Radar you want to apply on the basis of requirement. After picking the appropriate mmWare radar type, the application of the mmWare radar module can enhance the functionality to the next level.

 

Advantages of the mmWave Radar Module 

Here are the most common advantages of mmWave Radar that make the sensors superior:  

 

Less Interruption: Implementing mmWave radar module frequencies has several benefits. One of them is minimizing the unwanted interruption from other co-frequencies in the atmosphere at the radar frequency. The reduction of interruptions in the atmosphere of the Radar improves the efficiency of the spectrum.

Robustness: Compared to infrared sensors, a mmWave radar module is a robust option for sensors to avoid atmospheric conditions like dust, smoke, and fog.

Good functioning during distractions: One of the most attractive benefits of using a mmWave radar in sensors is that it can also function under distractions such as bright, dazzling, or no lights. Moreover, the mmWave Radar comes with an enclosed plastic casing that lets it function smoothly.

Antenna miniaturization with large bandwidth: The mmWave radar module has improved antenna miniaturization compared to other traditional radars with the help of centimeter waves. Additionally, its large bandwidth allows detailed structural features for the users by using broadband frequency modulation signals. 


Types of mmWave Radar Module

Below are the three types of mmWave Radar module to use for better functioning:

1. 24GHz millimeter wave radar 

The first type is 24GHz millimeter wave radar, a civilian wave radar with a 1.25cm wavelength. It is very cheap due to the frequency band being relatively low. Furthermore, the bandwidth is also very narrow (only 250 MHz), limiting the wave radar's measurement accuracy. 

2. 77GHz millimeter wave radar 

The second one is a 77GHz millimeter-wave Radar with a wavelength of only 3.9mm makes the frequency high with a bandwidth of 4GHz. The longer the wavelength of a radar, the less efficient it is. 77 GHz millimeter wave radar picked up 24GHz gradually from the market, becoming mainstream in the automotive field.

3. 60GHz millimeter wave radar

The 60 GHz mm radar has a benefit of up to 7 GHz, especially for short-range applications, to provide better resolution. It is mainly beneficial to cope with insufficient precision, 24 GHz radar bandwidth, and the limitations of object sensing. Similarly, it has made all the technology vendors compete by millimeters to gradually transfer from 24 GHz to 60 GHz.


Application of the mmWave Radar Module

In emerging technology, mmWave radars are the primary element in order to improve the measurement of distance, acceleration, velocity, and angle. Besides, it also enhances the usage of applications such as gesture detection, cloud sensing, automotive driving safety, medical observation, etc. 

 

MmWave radar module sends pulses of mm electromagnetic wave energy and detects targets from the reflections. In addition, numerous antennas are available to capture reflected signals. It is helpful to determine the time of flight of mmWave pulses, the angle of arrival, the target distance, and the relative velocity. Finding the position and motion makes mmWave Radar a good choice among the systems that sense the presence and behavior of humans or animals. 


Conclusion

The mmWave Radar module will be worthwhile for mainstream manufacturers with corresponding product development in the future. Millimeter wave is becoming one of the fastest developing technologies, with high demand for driving speed data, security, ultra-high definition multimedia, and surveillance to the next level.
