High frequency technology offers an extremely accurate distance measuring proximity sensor principle. In the close nearfield the resolution is better than 200 nanometer. The function is based on the shift of the resonance frequency of a cylindrical ceramic resonator by approaching conductive targets. Shown in the top photo is the electric field strength (red high, blue low) inside and outside the ceramic resonator. If a target enters the outside electromagnetic field of the sensor, the resonance frequency is shifted. The absolute value of the frequency shift determines the distance to the target. |

77GHz Automotive Radar Sensors* |
|
Stop and Go operation, Crash impact prediction, parking assistance |
|
Recent research into traffic flow has shown that a traffic jam with related accidents is mainly caused by uncontrolled braking and accelerating of the individual vehicles. Radar sensors which measure the distance to the vehicle in front, and record the relative speed, provide the data base for a regulating system which adjusts driving behavior automatically to the needs of the traffic flow. |
|
77 GHz radar sensors are available in state of the art technology: |
|
Compact planar design with microstrip patch antennas and active components mounted on antenna surface to fulfil high volume, low cost, fully automated production. |
|
Main specification data are: |
|
Transmitter operates at 76 to 77 GHz with FMCW modulation |
|
Stop and Go operationcovers a distance from 1 to 50 m and has in azimuth three 10° electronically switchable antenna beams at -10°,0°,+10°. |
|
Enhanced angle resolutionof 1° by computation of the several antenna beams between -10° to +10°. |
|
Parking assistancecovers a distance from 0 to 5 m and has in azimuth five 30° electronically switchable antenna beams at -60°,-30°,0°,+30°,+60° |
