The Gaussian pulse generator is the core component of the pulse ground penetrating radar
(GPR) system, which requires high amplitude, narrow pulse width, and low ringing levels …

This paper presents the design methodology for an antipodal Vivaldi antenna (AVA) catered
to emit an impulse-like waveform, relevant for near-field imaging in impulse-radio ultra …

In this paper, the method to design the antenna, which is suitable for an impulse-like
waveform radiation, is presented. In general, the impulse-like waveform has its spectrum of …

Currently, no publicly available comprehensive set of specifications exists for the design of
ground‐penetrating radar antennas. Specifications are presented and derived for the design …

A novel structure based on ultra-wideband (UWB) filtering circuit for isolation enhancement
of Vivaldi antenna with narrow gap in H-plane is proposed in this paper. An antipodal Vivaldi …

Nowadays, the development of sparse antennas with lower mass to replace conventional
ones while maintaining their performance is an important challenge to meet the …

Top-coal structure detection is an important basis for realizing effective mining in fully
mechanized cave faces. However, the top-coal structure is very complex and often contains …

The magnetic gradient tensor algorithm, which can quickly locate underground targets
without iteration, is constrained by positioning errors when detecting unexploded ordnance …

Ground penetrating radar (GPR) is an emerging technology for crop monitoring and
assessment in agriculture. The performance of GPR is directly related to its antenna …

In this research, a Vivaldi antenna was designed for ground penetrating radar (GPR)
applications which can work well at two band frequencies from 2.53-3.87 GHz and 5.276. 34 …
