RADAR APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18646218 titled 'RADAR APPARATUS
The radar apparatus described in the abstract generates multiple transmission signals with different start timings and applies phase rotations to some signals before transmitting them from separate antennas. The modulation frequencies of these signals also vary at specific timings.
- Signal generation circuitry creates multiple transmission signals with different start timings
- Transmission circuitry applies phase rotations to certain signals before transmission
- First and second transmission signals are transmitted from different antennas
- Second transmission signal starts later than the first
- Modulation frequencies of signals differ at specific timings

Original Abstract Submitted
A radar apparatus includes signal generation circuitry, which, in operation, generates a plurality of transmission signals transmitted at different transmission start timings, and transmission circuitry, which, in operation, applies different phase rotations to a first transmission signal and a second transmission signal among the plurality of transmission signals and transmits the first transmission signal and the second transmission signal from different transmission antennas. A transmission start timing of the second transmission signal is later than a transmission start timing of the first transmission signal. A part of the first transmission signal and a part of the second transmission signal are transmitted in a first period. A modulation frequency of the first transmission signal at a first timing included in the first period differs from a modulation frequency of the second transmission signal at the first timing.
