Steradian Semiconductors, a Bangalore based Indian startup, is developing a radar-based system which will help the vehicle to see better, and thus drive safer. The founders of the startup believe that there is a lot missing in the autonomous industry which is restricting the autonomous cars to become a reality. There are shortcomings in the sensors which are being used in the vehicles and they do not have any solution which is safe and cheap.

Some use sound to detect the surroundings whereas others use vision to monitor the roads and traffic lights. These sensors are used by various companies but others use either LiDAR or Radar technology.

Lidar is quite popular and the best example being the Google’s self-driving cars. Despite working at a low frequency, it is able to create an exact 3D map of the surrounding, detecting the sizes of the objects in the surroundings of the vehicle. But it is difficult to operate in foggy conditions, not to forget the cost of the Lidar is very high to be considered as an option to run in production.

Whereas radar can see through fog using radio waves which can bounce through the objects and calculate the time, speed and time of the object enabling to see it in every atmospheric condition including night. But it operates at a lower frequency than the lidar, also the viewing angle of the radar is very limited as compared to lidar.

High-resolution 4D radar

Steradian Semiconductors is a firm of five which is researching on a compact IC(integrated circuit) which will provide a high-resolution 4D imaging solutions suitable for autonomous vehicles. This consists of an IC and antennas, which work in tandem with an inbuilt camera and GPS to detect objects along the way.

This technology is still in research phase but a higher resolution solution might be a boost in the automotive industry.

Streredian aims to bring Radar revolution and aim to overcome the limitations by taking it to a level of a 4D mapping device than just an Obstacle detection sensor.

  • They claim to have developed worlds most compact 28nm Millimeter-wave Imaging Radar Chip.
  • Brings in Multi-Antenna Sensor array to maximize the coverage.
  • Inference of Objects by using Machine Learning Algorithms.
  • 79GHz  Operating frequency.
  • Low Power Consumption(Amount not mentioned).
  • Range: 50 meters.

Currently, it’s too early to say about the viability of the product as the project is still in ongoing stage, however, based on the video and the projection of output data, things are looking promising.

The Team looks very strong with a minimum of 8 patents on each name and maximum of 38 Patents held by Gireesh Rajendran, who is also CEO of the company. The prospectus of the product is going to be great if they are able to fill the gap in the sensor technology currently pertaining for self-driving cars to work on the commercial level.
