The UMRR-S: A High-Performance 24GHz Multi Mode Automo- tive Radar Sensor for Comfort and Safety Applications

The paper describes the UMRR-S sensor, which has been developed for automotive applications in a co-operation between Volkswagen AG and smart microwave sensors GmbH as a derivative of the UMRR platform. The sensor is able to operate in the 24GHz ISM band and is applicable for Advanced Driver Assistance System functions. It can run both in UWB Pulseand in a number of Narrowband FMCW Modes. It can be part of a network formed of several UMRR-S sensors, or integrated into an existing sensor network, for instance in combination with a 77GHz long range radar. Different types of antennae are available. Concept, technical and performance data of the sensor are given. Advanced features like object generation out of individual radar reflectors from one physical object are described. I. Concept and Technical Data The name UMRR stands for Universal Medium Range Radar. The design targets of the UMRR sensor platform were mainly flexibility and performance. Flexibility: UWB Pulseand FMCW narrowband operation possible. Multiple planar antenna designs available (independent of microwave module). Stand alone or network operation. No central ECU required for network operation. Performance: Direct an simultaneous measurement of range, velocity and angle. Short measurement time. Reasonable Minimum Range (0.75m), Medium maximum range (typ. 50-70m). Conformity with RegTP / ETSI EN 300-440 frequency regulations in FMCW narrowband mode. One-Box-Design with integrated detection, tracking and communication software. CAN Power Sensor-Processor #1 DSP Board RF Board DSP A
