Title:
TRANSMITTER, RADAR AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/133835
Kind Code:
A1
Abstract:
The present application relates to the field of radars, and discloses a transmitter, a radar and a vehicle, which are used for general purposes in scenarios that have various detection distances without reducing the efficiency of power amplification in the transmitter. The transmitter comprises a signal transmitter, a first sub-channel, a second sub-channel, a combiner and a transmitting antenna. The signal transmitter is used for transmitting a constant envelope transmission signal; the first sub-channel is used for carrying out power amplification and phase shifting on the constant envelope transmission signal so as to output a first transmission signal; the second sub-channel is used for carrying out power amplification and phase shifting on the constant envelope transmission signal so as to output a second transmission signal; and the combiner is used for combining the first transmission signal and the second transmission signal so as to output the combined transmission signal to the transmitting antenna.
