Radar Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 18456056 titled 'Radar Device
The radar device described in the patent application consists of a transmitting antenna unit, a modulator, a receiving antenna unit, a receiver, and a processor.
- The transmitting antenna unit includes transmitting antennas.
- The modulator generates transmission signals by executing phase-shift keying through diverging the common signal into diverged signals with rotated phases.
- The receiving antenna unit includes at least one receiving antenna.
- The receiver generates a received code by encoding an appearance pattern of at least one received signal on a Doppler frequency axis.
- The processor generates information related to an object based on the received code.
- The modulator uses a linear block code as an assigned code for phase-shift keying.
Potential Applications: - Surveillance and security systems - Autonomous vehicles - Weather monitoring and forecasting - Search and rescue operations - Traffic management and control

Original Abstract Submitted
A radar device includes a transmitting antenna unit, a modulator, a receiving antenna unit, a receiver, and a processor. The transmitting antenna unit includes transmitting antennas. The modulator generates transmission signals respectively provided to the transmitting antennas by executing phase-shift keying through diverging the common signal into diverged signals having the number being equal to the number of the transmitting antennas and rotating respective phases of the diverged signals. The receiving antenna unit includes at least one receiving antenna. The receiver generates a received code of at least one received signal. The received code is acquired by encoding an appearance pattern of a peak of at least one received signal on a Doppler frequency axis. The processor generates information related to an object, according to the received code generated by the receiver. The modulator executes the phase-shift keying by using a linear block code as an assigned code.
