A novel dual-tone CW radar is proposed. Six-port circuit is used as a mixer to obtain the phase difference and Doppler frequency difference between the received and transmitted signals, and then the range and relative velocity of the target can be calculated. An anti-noise method is also proposed according to the measurement process and noise transfer principle. Simulation results show that this proposed radar has a higher accuracy with a simpler measure procedure.
