Re: Antenna Ringing
As mentioned in the previous reply, it is a Radar teminology. When an ideal GPR antenna is excited, it radiates only during the duration of the excitation pulse. But in reality, the antenna continues to radiate even after the excitation pulse has
died down. This is due to the internal reflections of the charges that occur at the ends of the bowtie wings and the excitation points. The charges move back and forth in the bowtie wings, gradually decaying and radiating at discrete time intervals into the external media. This is known as antenna ringing.
Antenna ringing is undesirable as it corrupts the transmitted pulse waveform and reduces range resolution.
