Abstract

The invention discloses a two-dimensional angle measurement vehicle-mounted radar system, a radar two-dimensional angle measurement method and a storage medium. The two-dimensional angle measurement vehicle-mounted radar system comprises a transmitting module, a plurality of transmitting antennas, a plurality of receiving antennas, a receiving module and a signal processing module. The transmitting antenna is a 45-degree linearly polarized antenna; the transmitting module is provided with a plurality of output ports, and the transmitting module is electrically connected with the plurality of transmitting antennas through the corresponding output ports; and the receiving module is electrically connected with the receiving antenna and the transmitting module. The signal processing module is electrically connected with the transmitting module and the receiving module. According to the two-dimensional angle measurement vehicle-mounted radar system, at least two rows of receiving antennas are arranged in the vertical direction, and each row is provided with a plurality of receiving antennas, so that the radar system not only has an angle measurement function on an azimuth plane, but also has an angle measurement function on a pitching plane, and the detection performance of the radar is greatly improved.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a two-dimensional angle measuring vehicle radar system, a radar two-dimensional angle measuring method and a storage medium. Background technique [0002] Millimeter-wave radar is widely used in advanced driving assistance systems of automobiles due to its small size, light weight, and little influence from weather. At present, the common vehicle-mounted millimeter-wave radar system uses the frequency modulation continuous wave working mode, transmits the frequency modulation triangle wave or sawtooth wave through the transmitting antenna, and then processes the received echo signal by distributing multiple receiving antennas on the azimuth plane, so that Calculate the target's distance, speed and azimuth angle. There are two main disadvantages of such systems, one is that they lack angle measurement capability in the elevation direction, and the other is that the antennas of thes...
