de Groot, T.H. (author), Yarovoy, Alexander (author), Woudenberg, E (author)This paper proposes feature extraction methods for object classification with passive acoustic sensor networks deployed in suburban environments. We analyzed the emitted acoustic signals of three object classes: 1) guns (muzzle blast); 2) vehicles (running piston engine); and 3) pedestrians (several footsteps). Based on the conducted analysis,...journal article 2015

Penkin, D. (author), Janssen, G. (author), Yarovoy, A. (author)The power budget of a wireless link between two electrically small sensor nodes located close to an interface between two media is studied. The model includes both the propagation channel losses and input impedance of the radio frequency antennas. It is shown that a highly inductive half-space significantly enhances the received power due to the...journal article 2014

Penkin, D. (author), Janssen, G.J.M. (author), Yarovoy, A. (author)To effectively localise a source node in a dense wireless tiny-sensor network with an arbitrary 2D/3D node distribution, a novel approach suitable to describe the hop progress of source-to-sink path in such a system is proposed. In this approach, the network topology is described as a regular lattice and relates the statistical parameters of the...journal article 2014

He, Y. (author), Aubry, P. (author), Le Chevalier, F. (author), Yarovoy, A. (author)A new approach is proposed to extract the slow-time feature of human motion in high-resolution radars. The approach is based on the self-similarity matrix (SSM) of the radar signals. The Mutual Information is used as a measure of similarity. The SSMs of different radar signals (high-resolution range profile, micro-Doppler, and range-Doppler...journal article 2014

Amaldoss, S.E. (author), Tran, D.P. (author), Yarovoy, Alexander (author), Roederer, A.G. (author)The design of a planar dual-band wide-scan phased array is presented. The array uses novel dual-band comb-slot-loaded patch elements supporting two separate bands with a frequency ratio of 1.4:1. The antenna maintains consistent radiation patterns and incorporates a feeding configuration providing good bandwidths in both bands. The design has...journal article 2014

Groot, S. (author), Harmanny, R. (author), Driessen, H. (author), Yarovoy, A. (author)In this article, a novel motion model-based particle filter implementation is proposed to classify human motion and to estimate key state variables, such as motion type, i.e. running or walking, and the subject’s height. Micro-Doppler spectrum is used as the observable information. The system and measurement models of human movements are built...journal article 2013

Savelyev, T. (author), Yarovoy, A. (author)A fast imaging algorithm for real-time use in short-range (ultra-wideband) radar with synthetic or real-array aperture is proposed. The reflected field is presented here as a convolution of the target reflectivity and point spread function (PSF) of the imaging system. To obtain a focused 3D image, the proposed algorithm deconvolves the PSF out...journal article 2013

Amaldoss, S.E. (author), Yarovoy, A. (author)The effectiveness of a cavity for dual-band patch radiator with a frequency ratio of 1.65:1 is analysed. The use of cavities can help in maintaining impedance matching, reducing the levels of mutual coupling between the elements as well as in containing the surface waves, aspects vital to array performance. Results demonstrate that with the use...conference paper 2011
