The "KAT" - Automotive and RADAR Sensing

The "KAT"

The "KAT"  - Competence Centre & Initiative Automotive Technology

 Automotive Electronics -- One of the current growth markets for wireless and multimedia technology.

In 2008, IMST  establishes a centre of excellence for automotive technology, called "das KAT". The name has not been chosen by chance - as a catalyst speeds up processes, not consuming itself, "das KAT" is aimed to provide a development platform for companies and universities - true to the credo: develop jointly, market the solutions separately. Advanced communications, detection techniques, and procedures for wireless transfer of energy are the focus of the developments. This enables wireless communication systems, e.g.  car-to-car  (C2C) and car-to-infrastructure (C2I), communication and routing platforms. Moreover the development of new components for networking in the automobile sector is triggered, such as wireless sensor networks, tire pressure sensors, radar sensors for automotive and last but not least dedicated antennas.

RADAR Sensing Technology

The IMST has developed a radar demonstrator at 24 GHz to measure the distance and speed by the well-known FMCW-method. The device is well suited for driver assistance in cars. It can detect objects up to a distance of 30 m around the vehicle. In particular, safety features such as collision warning and avoidance, mitigation of the blind spot, but also support functions such as a parking-aid can be realised with this smart device. Moreover, there is a variety of applications in the industrial sector, wherever distances and velocities are to be measured accurately by means of microwaves. Equally conceivable is the use inside buildings and on the premises around them. The sensor operates in the 24 GHz ISM band.

The following specifications provide an overview of the functionality and specifications of the radar sensor:
