  • Signal processing apparatus of a continuous-wave (CW) radar sensing system
    Patent number: 10451723
    Abstract: The invention discloses a signal processing apparatus of a CW-radar sensing system, comprising of a transmitting unit, a transmitting antenna and a receiving device. The transmitting unit produces a first frequency conversion signal and a second frequency conversion signal which are transmitted by the transmitting antenna serially and alternatively. A receiving antenna respectively receives the echo signal of the first frequency conversion signal and the second frequency conversion signal, and a mixing-LPF (lowpass filtering) module mixes the echo signal with a first frequency conversion signal and a second frequency conversion signal which are produced by a local oscillator and carries out lowpass filtering for the signals as to obtain a beat frequency signal of the above signals.
