Abstract
A method is presented whereby a compact circuit generates bipolar VHF waveforms of which the relative duration and amplitude of the positive and negative half cycles are adjustable. This facilitates fine timing of the waveform for a time limited response when driving resistor-capacitor loads. Performance is verified by measurements on a system functioning as a ground penetrating radar system where the antenna presents such an equivalent load.
