Millimeter – wave radar market overview and future development prospects

1. Millimeter – wave radar can realize many functions of automatic driving.

  The ADAS used by ADAS are mainly cameras and millimeter – wave radar and laser and ultrasonic and infrared and so on. Millimeter – wave radar has a long transmission distance, low atmospheric attenuation and loss in the transmission window, and strong penetrability. It can meet the requirements of the vehicle’s adaptability to the all-day climate. The characteristics of the millimeter - wave itself determine the small size and lightweight of the millimeter - wave radar sensor. It makes up for the use of other sensors such as camera laser and ultrasonic and infrared and so on, which are not available in - vehicle applications.
 

   The millimeter – wave radar is installed on the car which can measure the distance, and relative speed between the radar and object being measured. Adaptive cruise control can be realized by using millimeter - wave radar, Forward Collision Warning, Blind Spot Detection, Parking Aid, Lane Change Assistant, ACC, and ADAS Function.
    The more common Millimeter – wave Radar for automobiles operates at 24GHz and 77GHz. The nearly 24GHz radar system mainly realizes close range detection. The 77GHz system mainly realizes long-distance detection.
 

2. Millimeter – wave radar market is vast.

    Due to the continuous improvement of the vehicle safety standards in various countries, active safety technology advanced driving assistance system has been developing rapidly in recent years. Because the millimeter - wave radar can work all day. It has become the mainstream choice recognized by automobile electronics manufacturers. There is huge market demand.
 

   Current car millimeter - wave radar in high - speed development, the general support functions of ADAS car will use 2 or 3 millimeter - wave radar. A new AUDI A4 using 5 millimeter - wave radar. The Mercedes s-class cars use 7 millimeter - wave radar. The next cycling by the average number of millimeter - wave radar will continue to grow. The demand for automotive radar PCB will also grow rapidly.

   Since Millimeter - wave radar sends and receives signals 24GHz and 77GHz. The radar PCB high-frequency circuit includes clock signal modulation amplifier filter antenna and other parts. PCB board and manufacturing process have higher requirements. Therefore, the automotive radar PCB will bring higher value. Such as Schweizer, which accounts for 30 percent of the global high-frequency PCB market. Electronic AG’s high-frequency PCB usually requires PTFE filled ceramic and glass materials to meet the design requirements higher than 77GHz.
 

3. Millimeter - wave radar plays a very important role in UAV and security and intelligent transportation and industrial and military fields besides automotive ADAS.

-UAV (unmanned aerial vehicle): The main applications are fixed height and obstacle avoidance.

- Security:  The main used for a security alert in some important areas.

- Intelligent transportation: The main used for vehicle detection and traffic volume survey and traffic incident detection and traffic induction and speed monitoring and electronic bayonet and electronic police and traffic light control and so on.
 

- Industry: The main used in industrial level gauge and excavator and bulldozer near the high – voltage wire tower for safe construction and production safety monitoring.

- Military: The main used in radar detection and missile guidance and satellite remote sensing and electronic countermeasures and so on.

     According to the above analysis. The development trend of millimeter - wave radar technology is to develop in the direction of a smaller size. Lower power consumption and higher integration degree and coexistence and integration of multiple technologies (higher cost performance).
