Radar Sensor with Frontal and Lateral Emission
First Claim
1. A radar sensor for recording the environment of a motor vehicle, comprising:
- transmission means for emitting transmission signals using several transmitter antennas;
receiving means for receiving transmission signals reflected by objects using several receiver antennas; and
signal processing means for processing the received signals, characterized in thatit is equipped with several transmitter and receiver antennas, each containing at least one individual transmitting or receiving element, referred to henceforth as an elemental emitter, which is located on the front or rear face of a level printed circuit board,it is equipped with at least one transmitter antenna and receiver antenna, each containing at least one elemental emitter located on the level printed circuit board, the antenna pattern of said antenna outside the radar sensor being tilted at a maximum angle of 45°
to the perpendicular on the board, andit is equipped with at least one transmitter and receiver antenna, each containing at least one elemental emitter on the level printed circuit board, the antenna pattern of said antenna outside the radar sensor being tilted at a minimum angle of 45°
to the perpendicular on the board.
