N2 - With the increasingly complex modern traffic environment and the rapid development of autonomous driving technology, the demand for millimeter-wave automotive radar sensors with high ranging accuracy and angular resolution has become increasingly prominent. In view of the miniaturization requirements of millimeter-wave radar, this paper designs a highly integrated 24GHz two-transmit four-receive FMCW radar transceiver front-end based on a millimeter-wave integrated circuit chip (MMIC). The transmitting chain is designed with a frequency synthesizer with modulation function, and the receiving chain adopts the super-heterodyne system. Tests show that the RF front-end transmit signal spurious suppression is better than 45dBc, the phase noise is better than -75dBc/Hz@1kHz, the output signal power is 2.21dBm, the bandwidth is greater than 250MHz, and the receive channel gain is 22dB. The system has the advantages of simple circuit structure and high integration, which provides a reference for the design of on-chip radar systems.
