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

Abstract:
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. However, the high cost and bulky characteristics of beam-steering systems have prevented their extensive application. 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

Abstract:
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 A simple approach is presented to implement an active aperture radar with a constrained beam-forming network that is adequate enough to generate multiple beams for atmospheric wind profiling. In this approach, elements of the antenna array are fed directly by dedicated transceiver modules, which are realized with commercially available communication components, making them low cost. A passive 2D beam-forming network distributes the exciter output signal and feeds the transceivers with appropriate phase distribution to generate different beams.

Abstract:
In the past few years, a large range of wireless signals such as WiFi, RFID, UWB and Millimeter Wave were utilized for sensing purposes. Among these wireless sensing modalities, WiFi sensing attracts a lot of attention owing to the pervasiveness of WiFi infrastructure in our surrounding environments. While WiFi sensing has achieved a great success in capturing the target's motion information ranging from coarse-grained activities and gestures to fine-grained vital signs, it still has difficulties in precisely obtaining the target size owing to the low frequency and small bandwidth of WiFi sign

Observation and monitoring of landslides and infrastructure is a very important basis for land planning, human activities, and safety. Geomatic techniques for deformation monitoring have usually involved GNSS and total station measurements or, more generally, expensive geodetic instruments, but other techniques, such as SAR (Synthetic Aperture Radar), can be efficiently applied. Using low-cost sensors could be an interesting alternative solution if the accuracy requirements can be satisfied.

Abstract:
Information on pavement layer thickness is crucial for estimating bearing capacity, assessing remaining service life, and strengthening planning. Traditionally, the pavement layer thickness is determined by extracting cores and digging test pits. These methods are destructive, require temporary road closures and subsequent repairs, and at the same time provide incomplete information as the data relates to a specific location. For this reason, ground-penetrating radar has become one of the most widely used methods for determining pavement layer thickness in recent decades. GPR is a non-destruct

The measurement of the directional wave spectrum in oceans has been done by different approaches, mainly wave-buoys, satellite imagery and radar technologies; these methods, however, present some inherent drawbacks, e.g., difficult maintenance, low-resolution around areas of interest and high-cost. In order to overcome those problems, recent works in the area proposed a motion-based estimation procedure using the vessel, or the floating facility, as a wave sensor, what was called wave-buoy analogy.

Abstract:
Abstract Deformation monitoring has been conducted on land for many decades to observe fluid movement in reservoirs, determine hydraulic fracture orientation, and confirm cap rock integrity. The three technologies currently in common use for land-based deformation monitoring are: electrolytic tiltmeters, GNSS and InSAR (Interferometric Synthetic Aperture Radar). Each technology has a different set of strengths and weaknesses, which are in many ways complementary. Tiltmeters have a high temporal rate and provide far higher precision than GNSS or InSAR but require careful instrument layout plann
