Radar system for use in driver assistance system of e.g. airplane, has signal processing device evaluating signal received by radar receiving antenna, and comprising directional transmitter and two sound converters |
摘要 |
<p>The system (1) has a radar device (2) with a radar transmitting antenna (3) for aligned transmission of electromagnetic radiation, and a radar receiving antenna (4) for aligned receiving of radiation. An acoustic transmitting device (6) produces an acoustic signal (8) with a frequency in an ultrasonic range of 30-1000 kilo Hertz. A signal processing device (13) evaluates the signal received by the receiving antenna. The acoustic transmitting device has a directional transmitter with certain direction characteristic, and two sound converters (7) designed as acrostic directional antennas. An independent claim is also included for a method for detecting a sensor blockade in a radar system.</p> |
