After comparing with the performance of double sideband modulation and single sideband modulation, Single sideband modulation based on phasing was used for RF pulse modulation, which can cut down the peak power of RF pulse transmitter and achieve a precise phase. 在分析双边带和单边带调制的性能后,采用移相法实现RF脉冲的单边带幅度调制,并给出了具体的实现算法和仿真。
