In the joint research project RADARAUGE', funded by the Federal Ministry of Education and Research (BMBF), the development of a phased array radar sensor operated at 79 GHz with active MEMS based micro-switches is targeted for automotive environmental recognition purposes. Basically, driver assistance systems need a narrow beam to detect objects at long distances and to reject reflections originating from objects located next to the road. To survey the traffic on several lanes in medium and short distances, however, a wide detection range is required. The movement of vehicles in the neighbourhood shall be monitored to support lane change manoeuvres etc. Both tasks can be covered by a phased array antenna, which provides electronic beam steering of a narrow lobe over a wide detection range. Beside the automotive application, the sensor can be used to detect wake-vortices of departing and landing aircrafts. This allows the optimization of the time intervals typically inserted between take-off and landing procedures.
