Abstract

The invention relates to a millimeter wave radar, an antenna switching method of the millimeter wave radar, an electronic device and a storage medium. The millimeter wave radar comprises a millimeter wave radar chip, a radio frequency switch, a transmitting antenna and a receiving antenna. Wherein the millimeter wave radar chip comprises at least one transmitting channel and at least one receiving channel, the input end of each receiving channel is connected with one receiving antenna, and the output end of each transmitting channel is connected with the input end of one radio frequency switch; the radio frequency switch comprises a plurality of output ends, and the output end of each radio frequency switch is connected with one transmitting antenna; wherein the millimeter wave radar chip is used for transmitting unit waveform signals to the radio frequency switch through the transmitting channel so as to adjust the working time sequence of each transmitting antenna connected with the radio frequency switch. According to the invention, the problem that the millimeter-wave radar system cannot give consideration to high-resolution and high-coverage detection in the prior art is solved, and the technical effect of improving the detection resolution and coverage of the millimeter-wave radar system is achieved.

Description

technical field [0001] The present application relates to the technical field of millimeter-wave radar, and in particular to a millimeter-wave radar, an antenna switching method of the millimeter-wave radar, an electronic device, and a storage medium.
