Abstract: An information processing device and method, a transmitting device and method, and a receiving device and method are disclosed for multiplexing transmission signals in the same channel. In one example, transmission signals are generated by performing chirp modulation on data to be transmitted, and the transmission signals are multiplexed by shifting transmission timings of a plurality of transmission signals in a time direction and transmitting the transmission signals. Further, a plurality of chirp-modulated transmission signals which are multiplexed by shifting the transmission timing in the time direction and transmitted from a transmission side are received, and the plurality of received transmission signals are dechirped at timings according to the transmission timings.

Abstract: To provide a radar device, capable of eliminating the influence based on the local feedthrough in the FMCW radar device. There is provided a radar device including: an oscillator configured to oscillate a local signal; a transmitting antenna configured to emit a transmission signal based on the local signal; a receiving antenna configured to receive a reflected wave in which the transmission signal is reflected from a target; a mixer configured to multiply the reflected wave and the local signal by each other to produce a multiplied signal; and a first shifter provided between the oscillator and the mixer and configured to shift a phase of the local signal.

Abstract: To provide a radar device capable of improving azimuth estimation accuracy by compensating the Doppler phase shift of a moving target in a TDMA FMCW MIMO radar device. Provided is a radar device that allows transmitting antennas to perform transmission by performing sequential switching such that antenna element numbers are anterior-posterior symmetrical centering on a reference time and synthesizes a beat signal at the reference time from a first beat signal received by a receiving antenna before the reference time and a second beat signal received after the reference time.
