基于延迟差分馈电的时域脉冲电场幅-频双维调控方法
Dual-dimensional amplitude-frequency enhancement of time-domain pulsed electric fields based on delayed differential feeding method
摘要
Abstract
[Background]Transient electromagnetic pulse generators are widely used in ground-penetrating radar and through-wall radar.[Purpose]Improving the output energy efficiency and repetition frequency of pulse radiators has become an urgent problem to be solved.To solve this issue,this paper presents a dual-dimensional control method based on delayed differential feeding.[Methods]By configuring a time delay,differential pulses with opposite polarities,equal amplitude and pulse width were adopted to excite the radiator synchronously or with a time shift.A pulse radiator and±6.4 kV pulse sources were manufactured for verification.Comparative experiments among single-channel feeding,power-combining feeding and the proposed scheme were conducted.[Results]Measurement results show that the radiated electric field strength increases by 109.6%against single-pulse feeding and 48.3%against power-combining feeding,and the repetition frequency increases by 100%.[Conclusions]This method avoids energy loss and reflection in power synthesis,and reduces design challenges from element spacing and mutual coupling in field synthesis.It realizes independent control over pulse amplitude and repetition frequency,and provides a simple and effective feeding solution to enhance the performance of transient electromagnetic pulse generators.关键词
