The invention discloses a short-distance target simulation method for an MFSK waveform radar, and the method comprises the steps: obtaining a transmitting signal of the radar, adding frequency deviation information into the transmitting signal, obtaining an echo signal of the transmitting signal, and reducing the distance of a nearest target object which can be simulated by a radar target simulator. Therefore, the nearest distance of the target object which can be simulated by the radar target simulator is not limited by the inherent time delay of ADC and DAC devices and the time delay of the signal processing unit any more. 本发明公开了一种针对MFSK波形雷达的近距离目标模拟方法，采用获取雷达的发射信号，在发射信号中加入频率偏移信息，得到发射信号的回波信号，达到缩小雷达目标模拟器能够模拟的最近目标物的距离的目的，从而实现了雷达目标模拟器能够模拟的目标物的最近距离不再受ADC和DAC器件固有延时和信号处理单元延时的限制。
