摘　　要：针对基于脉冲位置调制的超宽带尢线电发射系统中的跳时控制这一关键技术,提出了利用FPGA和可编程延时线实现跳时控制的方法,并制作了硬件电路。通过脉冲整形电路得到了跳时后的输出脉冲波形,并将跳时精度控制在50 ps左右。通过对波形中的干扰和跳时控制精度的分析,提出了可能出现的问题和解决方案。To solve the key technique of time-hopping control for TH-PPM UWB system, a new TH-control method is put forward, which uses programmable delay line and FPGA as the logic control components of the circuitry, and the hardware circuitry is implemented. An impulse generation circuit is used to get the impulse waveform, and the TH precision is controlled within 50 ps. Through analyzing the interference and the TH precision of the impulse, the problems that may appear in TH and the solutions to the problems are discussed.
