摘　　要：指出了距离跟踪对 SFP(步进频率脉冲 )雷达一维距离成像的重要性以及实验用成像方法的局限性。采用数字距离跟踪可以降低对 A/D转换器采样频率的要求 ,大大减少了成像的运算量。数字距离跟踪还可以对速度进行估计 ,从而对成像进行速度补偿。Range tracking is very important for stepped frequency pulsed (SFP) radar one dimentional range profile. Limitations of the range profile method used in our experimental radar are discussed. Adopting digital range tracking, the sampling rate of A/D converter and the operation needed can be reduced greatly. Digital range tracking can also be used to estimite the target velocity and make velocity compensation when range profile is made. A scheme of digital range tracking using single chip computer is presented.
