This work presents two different novel groundless absorber based sensor design to be integrated in a single mode waveguide. This metamaterial absorber is used in high resolution measurements of variations in the permittivity of the dielectric material ...

In this paper, the design of a forward-looking economical monopole antenna with an outer assembly diameter of 48 mm to be used for borehole radar applications is presented. Two comparable antenna designs, one with an air core and other with dielectric-...

The variety of fractal curve types opens up additional structural and electrodynamic possibilities in the design of antennas. The article describes experimental results of studying characteristics of different types of fractal antennas (fractal ...

This paper deals with the challenges of transmitter-receiver isolation in Continuous-Wave Radars. Based on a Full-Duplex configuration, the leakage power from typical modern radar components has been measured. The aim of this study is the suppression of ...

A synchronization approach is presented for a new modulation technique called Sigma Shift Keying (SSK). Advantages of SSK are minimal transmit power output and very low probability of intercept (POI). Digital modulation is performed by time-discrete ...

A MIMO system is a wireless system, which employs multiple antennas at the transmitter and the receiver. MIMO is an acronym for "multiple-input multiple-output". Its main objective is the transmission and reception of signals at the physical layer of ...

Recent research demonstrate the feasibility of spread spectrum techniques in a harmonic radar context. A mathematical model for an existing harmonic transponder tag is developed to facilitate the evaluation of these techniques. This is done using a ...

Airborne LiDAR data have advantages over passive remote sensing data in detailed description of vertical forest structure. LiDAR-derived information can potentially be used to solve such problems as forest type classification and forest boundary ...

Despite a huge stream of the experimental data, allowing us to estimate ionospheric parameters in near real time, necessity for ionospheric modeling does not decrease. Transition to developing a model of the most changeable structure - the main ...

The article explores the possibility of detection of people on the base of their sound shadow (sound blocking) when people cross the baseline in the Acoustic Forward Scatter Radar System (AFSRS). Experimental sound shadows have been obtained from moving ...

Due to the noise of various sources present in the interferograms and the differential interferograms, the detection of surface deformations by differential interferometry (DInSAR) is thereby a difficult and complicated task. However, the adoption of a ...

Drone technology can potentially be useful for land-borer security - unmanned drone missions could be performed in the sky, supported by embedded sensors and data processing. Algorithmic rules can be incorporated in the drone software to make instant ...
