4D Imaging Radar Systems: Adding Dimensions to Automotive Industry

Automotive 4D Imaging Radar

Recently, in response to the sweeping wave of wellness among people worldwide, a radar technology startup in South Korea, bitsensing, raised $10m to expand its 79GHz 4D imaging radar to indoor health applications. Although the company has already proven its potential by developing radar sensors for autonomous vehicles and intelligent traffic management, it now seeks to venture into another dimension.

But, if you are wondering what 4G Imaging Radar systems are, let us put them together in simple words. 4D radar is a technology that operates on the concept of time-of-flight measurement and echolocation to map objects in a 3D domain. Further simplifying, 4D Imaging Radar is a newer technology to existing Lidar, standard radar, and cameras often used in automotive applications. It amplifies the experience by precisely detecting the distance, relative speed, and azimuth of articles in the roadway. Also, it helps to identify the height of the objects above the road. In fact, the radar system is mandated by the European New Car Assessment Programme to get a 5-star safety rating.

Recent research published by Markntel Advisors reveals that Global Automotive 4D Imaging Radar Market might grow with a CAGR of around 20% during 2022-27. The rationale behind such significant growth lies in its ubiquitous applications and benefits. But, before jumping on to that, lets us understand how 4D Imaging Radar influences the automotive industry.

4D Imaging Radar in Modern-Day Automotive

Like any other radar, it captures the signal that bounce-off the objects in the vicinity & then calculates the direction, speed, location, size, & elevation of objects in the surrounding. For this, the 4D radar is equipped with Multiple Input Multiple Output (MIMO) antenna array. One of the incredible benefits of deploying 4D radar in cars includes the unmatched capability of maintaining accuracy & precision in case of unfavorable climatic conditions & superimposition of one object by another.

Various studies suggest that the capability of current generation radars or 2.5 radars swings between the availability & unavailability of an object & does not provide comprehensive coverage of the article in front of the vehicle. Perhaps, it is why the need for many advanced radars that offers compatibility with multiple dimensions has arisen substantially throughout the world.

  • Prominent brand, Steradian, introduced a 4D radar imaging radar that includes a front end, operating in millimeter waves in the 76 to 81 GHz band, which pairs up their custom radar perception software. The radar IC is an integrated 16-channel E-band MIMO radar transceiver that interfaces with the Imaging Radar Unit (IRU). The IRU supports multimode through its wide field of view (FOV), 120° in azimuth and 30° in elevation, & is capable of 4D imaging because of its antenna array, generating a 1.2° azimuth beam width.
Applications of Automotive 4D Imaging Radar

While applications like left-child identification and exterior & passenger monitoring are among the key areas hinting toward lucrative opportunities for manufacturers & investors in the coming years, Passenger Monitoring, in particular, projects for faster growth in the industry. Backed by its efficient operation of airbags & mandatory seatbelts wear in automobiles, the demand for 4D Radar Imaging Systems in Automotive find extensive application for passenger monitoring. Besides, the augmenting demand for more autonomous vehicles & ADAS systems are also influencing passenger monitoring purposes and shall have a remarkable adoption of 4D imaging radar in the coming years.

Moreover, other perks like keeping a close eye on drivers’ activities such as talking on the phone, mobile texting, eating, drinking, smoking, getting distracted, or falling asleep, among others, are further stimulating the need for advanced 4D imaging radar systems, promulgating the industry. For instance,

  • Recently, EKA, an electric vehicles & technology company and a subsidiary of Pinnacle Industries Ltd., announced a partnership with Newport robotics to introduce the level 2 ADAS for their electric bus models. The development of the ADAS system for level 2 electric buses would deploy 4D imaging radar technology for efficient monitoring of the passengers & exterior objects.
Summing Up

While radars have a history in the automotive sector, the latest 4D imaging radar systems have been an upgrade to the automotive industry, hinting toward remarkable sector growth in the coming years. Besides, because of the extreme usefulness in collecting & analyzing real-time information about the object in the environment, and the comprehensive coverage & adoption of these systems in automobiles, the Automotive 4D Imaging Radar Market is set to showcase a strong foothold in the coming years.
