Short Range Radar systems are the Ultrasonic radars having detection capacity less than 5
meters, predominantly used in blind spot and side impact detection. Also, these radars provide
parking assistance solutions. Severe government rules and regulations regarding automotive
safety is expected to fuel the installation of this equipment in the vehicles, which in turn may
boost the demand for ultrasonic radars over the forecast period.
The segment comprises of 24GHz and 77GHz chips. 24GHz variants are envisaged to find their
application in various systems such as Rear Pre-crash System (RPS), Lane Change Assist
(LCA) and traffic jam assist. It also assists drivers in lane-crossing by generating alerts about
the rear vehicles. 77GHz are primarily used in adaptive cruise control and autonomous
emergency braking (AEB) systems.
Stop & Go Adaptive cruise control system has two 24GHz chips on both sides and 77GHz radar
in the center. The arrangement helps in detecting object and distance in the periphery of around
100-150 meters from the car. However, inaccuracy of object classification and recognition
capabilities may act as a major hindrance in the growth of automotive radar market over the
years to come.
Various major players are now keen on developing next generation radars, such as 79 GHz
variant, which enables the drivers in executing semi-autonomous and autonomous decisions
efficiently. This system is competent in detectin g pedestrian and bicycle crossings and
delivering superior operational accuracy. Camera based systems are also anticipated to follow
positive growth arc on account of stringent government mandates for incorporating these
systems in the vehicle. Rapid Technological changes may further propel the demand for
distance warning as well as automatic emergency braking system in the near future.
On the basis of range, these devices can be further classified into Narrowband (NB) and ultrawide band (UWB). They are driven by their ability to deliver greater accuracy in object detection
and tracking. They offer greater degree of autonomy while driving by providing simultaneous 3D
