模拟器件的非理想因素和电路分布参数等影响造成了特形脉冲调制时的射频泄漏；这些射频泄漏将对特形脉冲的激发轮廓产生缺陷．本文从特形脉冲的射频调制原理着手，分析了射频泄漏对选择激发轮廓的影响．并采用一种新的相位循环方法对它进行补偿．实验的结果表明这种补偿方法有一定的实用性．
The effects of non-ideal components of the analog device and circuit distribution parameters cause radio frequency leakage at the shaped pulse modulation; these RF leakage will cause defects in the excitation pulse of the shaped pulse. In this paper, the principle of RF pulse modulation is studied. The influence of RF leakage on the selection of excitation profile is analyzed. And uses a new phase-loop method to compensate it. The experimental results show that this compensation method has some practicality.
