A new solver based on an improved Chebyshev spectral method is proposed to simulate the atmospheric propagation in the case of parallel-plane atmosphere, Rayleigh scattering, and a Lambertian surface at the bottom of the atmosphere. A numerical validation is achieved against a publicly available benchmark dataset and an analysis of the...

An improved spectral coefficient method based on Chebyshev polynomials of the second kind is employed to solve the vector radiative transfer equation under the assumption of parallel-plane atmosphere and Rayleigh scattering. The solver is extended to consider a Lambertian surface at the bottom of the atmosphere. The computational properties of...

In this paper, a microwave imaging method able to inspect three-dimensional configurations is proposed. The approach is developed in Lp Banach spaces, and allows to suitably face the ill-posedness of the considered full vector inverse scattering problem. The assumed nonconventional spaces require several modifications in the original...

Correct regulation of meteoric surface and subsurface flow waters is a fundamental goal for the sustainable development of the territories. A new system, aimed at real-time monitoring of the rainfall and of the cumulated rainfall, is introduced and discussed in the present paper. The system implements a Sensor Network based on the IoT paradigm...

An increasing number of practical applications of three-dimensional microwave imaging require accurate and efficient inversion techniques. In this context, a full-wave 3D inverse-scattering method, aimed at characterizing dielectric targets, is described in this paper. In particular, the inversion approach has a Newton-based structure, in which...

An inverse scattering procedure for addressing three-dimensional microwave imaging problems is presented in this paper. The approach is based on the full-vector integral formulation of the scattering phenomena and exploits the regularization capabilities of a Newton scheme integrating a conjugate-gradient approach developed in Lp Banach spaces....

A prototype of a radar system for classification of multiple targets passing through a road gate is presented in this paper. It allows to identify different types of targets, i.e., pedestrians, motorcycles, cars, and trucks. The developed system is based on a low-cost 24 GHz off-the-shelf FMCW radar, combined with an embedded Raspberry Pi PC...

This paper presents a filtering method to clean the backscattered signal received by a reader of frequency-coded cross-polarized chipless RFID tags. The proposed approach eases an automatic decoding of the received signal, and it is based on a proper time-frequency representation. Preliminary tests with both simulated and experimental data...

An approach for monitoring the respiratory rate based on impedance measurements is presented in this paper. In order to possibly obtain a minimally-invasive wearable device, the electrodes are located on the head, near mastoid bones, and measure the variations induced in the electrical impedance by the physiological changes in the pharynx...

The treatments for brain stroke are strongly timedependent. The medical literature highlights the need of a quick diagnosis in order to guarantee the most effective therapy. An important target for strokes is trying to achieve a Door-to-Needle (DTN) time of less than 60 minutes, which is called Golden Hour [1]. This paper proposes a mobile...
