摘要： A method and system for joint radar communication for automotive applications. The system carries out the method and includes a transmitter transmitting a radar signal, which signal has a phase-modulated continuous waveform and includes information encoded by phase modulation, a receiver, spaced from the transmitter, receiving the signal, and the receiver detecting the information from the received signal. In order to provide an efficient concept for joint radar-communication for automotive applications, the signal is a multi-carrier phase-modulated continuous waveform having a plurality of carrier frequencies and the information is encoded onto each carrier frequency.

摘要： A method of sensing a target in a target detection system having processing circuitry and a multiplexer coupled to the processing circuitry and to a plurality NT of transmit antennas forming a sparse transmit uniform linear array (ULA), the multiplexer being configured to generate multiplexed and phase modulated transmit signals (T1 . . . TNT) based on signals from a local oscillator. The processing circuitry receives signals via a plurality NR of receive antennas forming a dense receive ULA. The method includes transmitting the transmit signals via the transmit antennas as a general radiation pattern corresponding to a block circulant probing signal matrix, and receiving via the receive antennas receive signals resulting from backscattering of the transmit signals transmitted towards K targets. The method further includes processing the received reflection signals to determine the presence, range and/or angular position of a target within a field of view of the transmit antennas.
