Track-before-detect (TBD) algorithms make use of unthresholded measurements to perform target detection and tracking in scenarios where conventional approaches fail, as it is the case for low signal-to-noise ratio (SNR) conditions. In this paper, the track-before-detect algorithm using particle filters is applied for target detection and tracking and its performance using real-world radar data is assessed.

This paper presents a method to measure the radar cross section of a disk (with known radius) at normal and oblique incidence in the Fresnel region and real environment. The proposed method relies both on the physical optics approach and averaging the field distribution over the transmitting and receiving antenna apertures. The ratio between the analytical expression of the radar cross section at far-field and Fresnel region results in a transformation factor between both field zones. The RCS obtained through scattering parameters measured at Fresnel region distances is corrected with the analytical transformation factor previously determined. The measurements are in a good agreement with simulations and theoretical far field radar cross section at normal and oblique incidence.

Improvements to measurements of a VHF folded dipole operating at 55–65 MHz to be used as part of a radar for a mission to one of Jupiter's moons, Europa, are presented. Previous measurements using an unmanned aerial vehicle (UAV) or small unmanned aerial system (sUAS) are improved upon by reducing systematic errors and more accurately tracking distances within the measurement system on an outdoor measurement range at Jet Propulsion Laboratory (JPL). Details of the measurement system setup are presented along with a brief discussion of error sources. Comparing previously collected measurement data with the new measurements reveal an improvement of approximately 0.4 dB in accuracy with an improvement in over 1 dB for error budgets.

This paper proposes a single coaxial feed rectangular microstrip antenna aiming at GPS application. The antenna has a simple design with conventional FR4 substrate which is easy to be fabricated. Computer Simulation Technology (CST) Microwave Studio software is used to numerically design the antenna. The proposed antenna has rectangular patch with rectangular slots in the middle and the edge of the patch. The antenna has a working frequency of L1 band GPS (1575 MHz), Coaxial feeding technique is applied to affect the current distribution and resulting in right-hand circular polarization. Simulated results indicate that the proposed antenna has achieved the desired specifications with S11 of −44.07 dB, axial ratio of 1.52 dB, bandwidth of 46.8 MHz and gain of 3.071 dB. The proposed design is fabricated and the measurement results agree with the simulated and achieve all of desired specification.

The standard method for assessing the specific absorption rate of a mobile device involves scanning an electric field probe in a tissue equivalent liquid. The electric field probe is also calibrated in the liquid. Uncertainty of permittivity measurement of the liquid accounts for a large proportion of uncertainty of the specific absorption rate measurement and related probe calibration. The permittivity measurement of the liquid generally employs a coaxial probe method, but its uncertainty tends to be somewhat large because of its reflection measurement. In this paper, we propose a method to estimate the complex permittivity of the liquid from the attenuation and phase constants of the liquid surrounded by the waveguide well and moving the small dipole antenna in it, and show an example of actual measurement.

This work presents the design of a compact meander-based antenna for search and rescue application. The proposed antenna is designed on a polydimethylsiloxane (PDMS) substrate, which is robust, flexible, waterproof and suitable for use in harsh environments. Due to the need for operation at a relatively low frequency of 406 MHz, antennas for the search and rescue application require an extended electrical length, thus typically resulting in large sizes. This is alleviated by implementing the meander-based structure on the antenna to ensure size compactness. Besides that, to minimize the effects of the human body when worn, the antenna is integrated with a full ground plane on its reverse side to shield the body from electromagnetic coupling. Results indicated that the antenna operated with a center frequency of 406 MHz and bandwidth of 30.88 MHz (7.61 %). A unidirectional radiation is produced and the final size is 190 × 60 × 5 mm (0.257 × 0.081 × 0.0068) λo.

Radar can be used for concrete inspection application to prevent structural failures. One of its components is the antenna. In this paper, a design of 1×4 microstrip array antenna integrated with unequal Wilkinson power divider using Dolph-Chebysev method on Epoxy FR-4 substrate with a dielectric constant of 4.3 was developed. Antenna is designed and simulated using CST software. The working frequency is in the ISM Band of 2.4–2.5 GHz with return loss −10 dB. The simulation results show that the array antenna operates at frequency 2.34–2.58 GHz or bandwidth of 243.6 MHz. In addition, the antenna has a gain of 4.39 dB, horizontal beamwidth of 27.8°, vertical beamwidth of 130.8°, front-to-back ratio of −21.87 dB, and sidelobe level of −13.2 dB. The measurement results show that the array antenna operates at frequency 2.35–2.59 GHz or bandwidth of 233 MHz. Moreover, the antenna has gain of 5.12 dB, horizontal beamwidth of 26°, vertical beamwidth 70°, front-to-back ratio of −20.22 dB, and sidelobe level of −17.45 dB.

An 868MHz-915MHz 16-elements helical wire antenna array design with a solar-cell integration is presented. Each element is designed to be omni-directional with the corresponding tuning stubs and ground substrate. This is shared with distributed solar cell array, powering 16- Internet of Things (IoT) transceivers operating at multiple Industrial Scientific and Medical (ISM) bands. 370mm×400mm design including the antennas, solar cells, and the tuning stubs can generate 8-watts solar power under direct sun, charging Lithium batteries. 1.6-mm thick planner design with horizontal radiation pattern resulted in average −15dB return loss at 868-MHz without using any external matching elements.

A UWB bow-tie antenna, designed to work in the VHF -UHF band, is realized by a novel implementation of tapered inductive loading. The antenna with the proposed loading profile has been manufactured as a printed antenna on an FR4 material. It exhibits a fractional bandwidth of over 90% with dimensions of only 20×20 cm for a center frequency of 450 MHz. Despite its relatively small size, the proposed antenna works with very high efficiency, as the proposed loading scheme introduces no ohmic loss. In principle, it can be applied to other frequency bands as well, by scaling the antenna dimensions up or down according to the desired center frequency. Additionally, resistive loading such as microwave absorbers can be added when a larger bandwidth is needed.

This paper analyses the performances of a Direction of Arrival (DoA) localization algorithm based on the use of phaseless magnitude data coming from a Time of Arrival (ToA) estimation. The localization system architecture key component consists of a broadband switched beams antenna (SBA) connected to a corresponding broadband radio front-end. The receiver collects sample data being synchronized with the antenna beam, while both ToA and DoA estimations rely only on scalar data. Differently from the available literature, the proposed system doesn't locate the DoA by implementing the Time Difference of Arrival (TDoA) paradigm, but instead this is made possible by using the phaseless data of the impinging signal power, exploiting the signal magnitude gradient between SBA elements, a byproduct of the ToA estimation. Experimental results demonstrate how different algorithms lead to an angular precision with a mean error inferior to 3°.
