Incorporating cyclone risk in the design of marine protected and conserved areas as an ecosystem‐based adaptation approach

Conservation Biology, EarlyView.
Abstract Marine protected and conserved areas (MPCAs) are promoted as an ecosystem‐based adaptation (EbA) approach to increase community and ecosystem resilience to climate change. However, traditional approaches to MPCA design typically do not consider climate risk or habitat condition under a climate threat.

LPI Sequences Optimization Method against Summation Detector Based on FFT Filter Bank

Remote Sensing
Waveform design is a crucial factor in electronic surveillance (ES) systems. In this paper, we introduce an algorithm that designs a low probability of intercept (LPI) radar waveform. Our approach directly minimizes the detection probability of summation

LPI Optimization Framework for Target Tracking in Radar Network Architectures Using Information-Theoretic Criteria

International Journal of Antennas and Propagation, 2014
Widely distributed radar network architectures can provide significant performance improvement for target detection and localization. For a fixed radar network, the achievable target detection performance may go beyond a predetermined threshold with full

Tracking individual Bactrocera tryoni: Wind effects and natural movement

Entomologia Experimentalis et Applicata, EarlyView.
Modeling insect movement relies on accurate characterizations of natural step distances, turning angles, and speed. Harmonic radar was used to observe male Queensland fruit fly (Qfly), Bactrocera tryoni (Diptera: Tephritidae), movements (natural and disturbance‐induced) in papaya (Carica papaya, Caricaceae).

Introduction to Noise Radar and Its Waveforms

Sensors, 2020
In the system-level design for both conventional radars and noise radars, a fundamental element is the use of waveforms suited to the particular application. In the military arena, low probability of intercept (LPI) and of exploitation (LPE) by the enemy

A generalized multivariate Student-t mixture model for Bayesian classification and clustering of radar waveforms [PDF]

arXiv, 2017
In this paper, a generalized multivariate Student-t mixture model is developed for classification and clustering of Low Probability of Intercept radar waveforms. A Low Probability of Intercept radar signal is characterized by a pulse compression waveform which is either frequency-modulated or phase-modulated. The proposed model can classify and cluster

Prospective neuroimaging and neuropsychological evaluation in adults with newly diagnosed focal epilepsy

Epilepsia, EarlyView.
Abstract Objective Few prospective studies exist on newly diagnosed focal epilepsy (NDFE), a critical period for understanding epilepsy's biology and identifying biomarkers and potential interventions. We report a prospective cohort study in patients with NDFE and age‐, sex‐, and education‐matched healthy controls.

Evolution of Netted Radar Systems

IEEE Access, 2020
The netted radar systems are known for being able to provide higher target detection probabilities, more accurate measurements, and better multi-target tracking performance than the monostatic/bistatic radar systems by exploiting information fusion ...

On the anti‐intercept features of noise radars [PDF]

Robustness against Electronic Warfare/Electronic Defence attacks represents an important advantage of Noise Radar Technology (NRT). An evaluation of the related Low Probability of Detection (LPD) and of Intercept (LPI) is presented for Continuous ...

Ensemble prediction for nowcasting with a convection-permitting model—I: description of the system and the impact of radar-derived surface precipitation rates [PDF]

, 2010
A key strategy to improve the skill of quantitative predictions of precipitation, as well as hazardous weather such as severe thunderstorms and flash floods is to exploit the use of observations of convective activity (e.g. from radar).
