摘　　要：简单介绍了V-调频信号的时频特点,以及V-调频信号对距离-速度二维信息的测量。研究了移频干扰对V-调频信号的干扰效果。针对移频干扰,利用V-调频信号的脉压特点,提出了一种抗移频干扰的方法,通过该方法,能够从受到移频干扰的V-调频信号的回波中获得单个运动目标的距离和速度信息。最后,通过仿真验证了这一结论。The features of V-FM signal in time domain and frequency domain are introduced. The measure of distance and velocity with V-FM signal is also analyzed. The effect of ruing on V-FM signal is studied. With the characteristics of pulse compression, frequency-shifting jam- a method of countering frequency-shifting jamming is proposed. The distance and velocity information of the single can be obtained from the echo of V-FM signal affected by frequency-shifting jamming with Finally, numerical simulations have verified the correctness of this method
