DEUTA Radar Sensors

Precision in the measurement of speed, distance and position

DEUTA radar sensors provide a contact-free way of measuring speed and distance by using the doppler principle of microwaves. The integrated Digital Signal Processor (DSP) is able to perform challenging evaluation algorithms to achieve high precision and high security without an extra evaluation unit.

Application in Vehicle Control

DEUTA Doppler radar sensors are used in railway vehicles on a grand scale as well as in automation and R&D. The use of DEUTA sensors means maximum flexibility and safety for vehicle control.

Single-channel Doppler Radar Sensor: DRS4

The DRS4 is special solution for traction control on cargo trains. The used patented algorithm for assessing instantaneous velocity was specially optimised for applications such as traction control and measuring at high rates of acceleration.

Dual-channel Doppler Radar Sensor: DRS05

The dual-channel Doppler radar  DRS05 uses special dual-beam algorithms to analyse the Doppler signals. These are optimised for high accuracy and a velocity measuring range of up to 600 km/h. The information is transmitted in data packages via a serial RS485 interface. The protocol is adapted for particular customer requirements and contains information on the evaluation status of the Doppler signals. Parameters derived from the speed, such as distance and acceleration are provided there. 

Information on the state of the DRS05 radar sensor is communicated alongside speed, distance, direction of travel and acceleration on the serial interface for a high level of security.

Robust design for long operating lives

With its integrated protective hood the Doppler radar DRS05/1S1 shows increased availability in winter conditions. The housing also increases operating life when the radar is subject to impacting stones. This solution is recommended for use in high speed trains with ETCS-/ERTMS systems.  If it is not possible to mount the unit into the cladding of the underbody, an optional protective cover (tested up to 400 km/h) can be mounted. 

Using microwave technology the DEUTA radar sensor is not influenced by spoiling compared to optical sensors.
