Abstract
A test device for a frequency modulated continuous wave (FMCW) radar is provided. The test device has a central control unit for monitoring the FMCW radar. When the FMCW radar transmits a frequency modulated continuous signal to search for a target, the central control unit of the test device in present invention will simulate the motion of the target according to a plurality of setting parameters and generate an echo signal to the FMCW radar. The present invention also includes a first digital signal synthesizer and a transmitting unit. The first digital signal synthesizer is coupled to the central control unit for generating and transmitting an intermediate-frequency signal to the transmitting unit according to the settings in the central control unit and a reference clock. The transmitting unit generates the echo signal according to the intermediate-frequency signal.
