Abstract:

Low Cost Ais System for Safe Navigation Automatic Identification System (AIS) ensures automatic transfer of information between sea going vessels and land based monitoring centers. AIS transceivers are obligatory on board vessels of 300 gross register tones and over. System supports safe navigation at confined and open areas, whilst on the former mentioned is especially helpful due to limited range of radar. Article presents low cost AIS system for small vessels and leisure crafts where AIS is not obligatory but might be valuable navigational aid. Some aspects concerning accuracy are presented

Abstract:

A primary concern in a multitude of industrial processes is the precise monitoring of gaseous substances to ensure proper operating conditions. However, many traditional technologies are not suitable for operation under harsh environmental conditions. Radar-based time-of-flight permittivity measurements have been proposed as alternative but suffer from high cost and limited accuracy in highly cluttered industrial plants. This paper examines the performance limits of low-cost frequency-modulated continuous-wave (FMCW) radar sensors for permittivity measurements. First, the accuracy limits are i

Abstract:

The system architecture for cognitive radar-communication (CRC) transceiver is proposed. A cognitive waveforms design approach, which is suitable for simultaneously performing both data communication and target detection, is presented. This approach aims at estimating target scattering coefficient (TSC) from the radar scene and facilitating high data rate communications. In order to minimize the mean square error (MSE) of the TSC, a convex cost function is established. The peak to average power ratio- (PAPR-) constrained optimal solution is achieved by applying the Kalman filtering-based strat

Phased array technology features rapid and directional scanning and has become a promising approach for remote sensing and wireless communication. In addition, element-level digitization has increased the feasibility of complicated signal processing and simultaneous multi-beamforming processes.

In this paper, an X-band element-level digital phased array radar utilizing fully integrated complementary metal-oxide-semiconductor (CMOS) transceivers is proposed for achieving a low-c

Direction-of-arrival (DOA) estimation is one of the most critical technologies of radar, remote sensing, and wireless communications. The traditional DOA estimation is closely related to phased array antennas, which require complicated and expensive hardware and high-power consumption. Metasurface can manipulate electromagnetic waves without using massive transceivers, which makes it possible to realize antenna arrays in a cost-effective way. Here, we propose a strategy of DOA estimations by using a time-domain-coding digital metasurface and a single receiver. Specifically, the incident wave o

Abstract:

This study investigates the application of a terrestrial structure from motionmulti-view stereo (SfM-MVS) approach combined with ground-penetrating radar (GPR) surveys for monitoring the surface topographic change of two permanent ice deposits in caves located in the Julian Alps (south-eastern European Alps). This method allows accurate calculation of both seasonal and annual mass balance, estimating the amount of ice inside caves. The ground-based SfM approach represents a low-cost workflow with very limited logistical problems of transportation and human resources and a fast acquisition time

            <strong>1.</strong><strong>INTRODUCTION </strong> Risks are present in all parts of the construction work regardless of size, resources, funds etc. Since each construction project is unique and dynamic, the construction performance presumes several uncertainties about the complexity of the construction project (Chandra, 2015). Risk management suggests that risks should be distributed to minimize their harm since they cannot be completely eliminated, which would have been the easiest option (Szymański, 2017). To amplify the prof
