Basic Radar System for Automotive ADAS
An automotive radar system is a safety system used for assisting drivers on the road. It helps drivers to virtually look at the cars or other vehicles and sense the stationery and moving 0bjects on the road. With advancements in the antenna design and semiconductor manufacturing of the radar system, its cost is drastically reducing. This is why a radar system is an ideal solution for automotive ADAS applications.
A basic Radar system is further classified into 3 categories:-
- Short Radar Range (SRR) – 0.5 – 20 meters
- Medium Radar Range (MRR)- 1- 60 meters
- Long Radar Range (LRR) – 10 – 250 meters
Some features of the Radar system are as follows:-
- Blindspot detection
- Traffic sign recognition
- Lane departure warning/ correction
- Park assists
- Pedestrian detection/ avoidance
One of the key applications of radar systems in ADAS is object detection and blind-spot monitoring. Object detection helps to locate and identify a nearby object whereas blind-spot monitoring helps to detect vehicles on the adjacent lane.
Some of the advantages of the Radar system are as follows:-
- A radar system can detect multiple vehicles simultaneously on the road.
- Radars can easily differentiate between moving objects and stationary objects which the proximity sensor-based system cannot.
- 3D images can be created using a radar system if used together with the existing camera-based system.
- It easily measures the accurate velocity and exact position of the nearby vehicle.
