A Low-Complexity Radar Detector Outperforming OS-CFAR for Indoor Drone Obstacle Avoidance [PDF]
arXiv, 2021 As radar sensors are being miniaturized, there is a growing interest for using them in indoor sensing applications such as indoor drone obstacle avoidance. In those novel scenarios, radars must perform well in dense scenes with a large number of neighboring scatterers.

Manoeuvre detection in Low Earth Orbit with Radar Data [PDF]
arXiv, 2022 This work outlines and assesses several methods for the detection of manoeuvres in Low Earth Orbit (LEO) from surveillance radar data. To be able to detect manoeuvres, the main starting assumption is that the object under analysis has an orbit known with a sufficient degree of precision. Based on the precise (a posteriori) orbit and radar data, several

Journal of Applied Ecology, EarlyView.Data from automatic detection systems are a promising non‐invasive approach that requires few human and logistical resources to develop a more comprehensive bird collision risk mitigation strategy. They can be valuable to biodiversity stakeholders to highlight environmental factors that locally increase bird exposure and sensitivity, to avoid ...

Automatic LPI Radar Signal Sensing Method Using Visibility Graphs
IEEE Access, 2020 The issue of the low probability of intercept (LPI) radar signal sensing has received considerable attention. Furthermore, the development of military technology further increased demand for it in future electronic warfare (EW).

Sensitivity of Single-Pulse Radar Detection to Radar State Uncertainty [PDF]
arXiv, 2022 Mission planners for aircraft operating under threat of detection from ground-based radar systems are often concerned with the probability of detection. Current approaches to path planning in such environments consider the radar state (i.e. radar position and parameters) to be deterministic and known.

Classifying low probability of intercept radar using fuzzy artmap [PDF]
, 2012 Electronic Support (ES) operations concern themselves with the ability to search for, intercept, track and classify threat emitters. Modern radar systems in turn aim to operate undetected by intercept receivers.
