Introduction to Coastal HF Maritime Surveillance Radars
Polish Maritime Research, 2019 This paper presents the main technical characteristics and working performances of coastal maritime surveillance radars, such as low-power High-Frequency Surface Wave Radars (HFSWR) and Over the Horizon Radars (OTHR). These radars have demonstrated to be

Source separation and localisation via tensor decomposition for distributed arrays
The Journal of Engineering, 2019 This study focuses on the problem of power spectra separation and localisation of multiple sources using distributed arrays. First, the array structure and signal model are discussed. By cross-correlating the multi-channel received signals in time-domain,

DoA Estimation via Unlimited Sensing
2020 28th European Signal Processing Conference (EUSIPCO), 2021 Direction-of-arrival (DoA) estimation is a mature topic with decades of history. Despite the progress in the field, very few papers have looked at the problem of DoA estimation with unknown dynamic range. Consider the case of space exploration or near-field and far-field emitters.

Large Direction-of-Arrival Mismatch Correction for Adaptive Beamforming
IEEE Access, 2022 Direction-of-arrival (DOA) mismatch can degrade the performance of adaptive beamforming algorithms. Thus, a projection method is proposed to correct this mismatch.

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection
Advanced Materials, EarlyView.Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Improved scheme for clutter rejection and DOA estimation in passive radar
The Journal of Engineering, 2019 Targets are hard to be detected by passive radars unless clutter, namely direct-path signal and multi-path signal, is suppressed. The subcarrier-based spatial adaptive processing is a high-performance spatial-domain clutter rejection algorithm.

Queue, 2007 It looks like today is finally the day that we all knew was coming. It was only a matter of time. An ambulance has just pulled up to haul away Marty the Software Manager after his boss pummeled him for failing to deliver on promises of money savings, improved software reuse, and reduced time to market that had been virtually guaranteed merely by ...
