The invention discloses a frequency-change radar goal emulator of millimeter wave, which comprises the following parts: control unit, transceiver unit, Doppler analog unit, distant analog unit and amplitude analog unit, wherein the radar signal enters into the Doppler analog unit through transceiver unit, which produces middle-frequency signal through lower frequency-changer and low-pass filter ofthe Doppler analog unit; the upper frequency-changer and band-pass filter group of Doppler analog unit produces RF signal; the difference of local oscillator frequency of upper and lower frequency-changers analogs the Doppler frequency shift of goal; the RF signal generates launching signal through changing the echo amplitude of goal simulated by amplitude analog unit, which is transmitted by transceiver unit; the control unit transmits control signal for other four units according to the analog parameter such as input distance, speed and amplitude; the radar signal passes the emulator to provide an analog signal with Doppler frequency shift, signal amplitude fluctuation and distant delay to radar, which provides estimating platform for working property testing for radar.
