A probabilistic hypothesis density filter for traffic flow estimation in the presence of clutter [PDF]

, 2012
Prediction of traffic flow variables such as traffic volume, travel speed or travel time for a short time horizon is of paramount importance in traffic control.

Knowledge-aided Bayesian covariance matrix estimation in compound-Gaussian clutter [PDF]

, 2010
We address the problem of estimating a covariance matrix R using K samples zk whose covariance matrices are kR, where k are random variables. This problem naturally arises in radar applications in the case of compound-Gaussian clutter. In contrast to the

Clutter rejection for MTI radar using a single antenna and a long integration time [PDF]

, 2011
Moving Target Indicators (MTI) are airborne radar systems designed to detect and track moving vehicles or aircrafts. In this paper, we address the problem of detecting hazardous collision targets to avoid them.

A comparative study of linear and region based diagrams

Journal of Spatial Information Science, 2015
There are two categories of objects spatial information science investigates: actual objects and their spatial properties, such as in geography, and abstract objects which are employed metaphorically, as for visual languages.

Comparison of Real Experimental and Simulated RCS of Flying Artillery Projectile [PDF]

Journal of Electromagnetic Engineering and Science, 2023
This study compares the actual experimental and simulation data of artillery projectiles (M107 projectiles) fired by a 155-mm gun. The experimental data are collected using a weapon-locating radar developed by LigNex1.

Improved entropy-based autofocus correction for synthetic aperture radar

The Journal of Engineering, 2019
Autofocus is an essential step in order to obtain the well-focused synthetic aperture radar image. Compared to the non-parametric autofocus, the parametric way is not subjected to the prominent targets so much.

Clutter Elimination and Random-Noise Denoising of GPR Signals Using an SVD Method Based on the Hankel Matrix in the Local Frequency Domain

Sensors, 2018
Ground-penetrating radar (GPR) is a kind of high-frequency electromagnetic detection technology. It is mainly used to locate targets and interfaces in underground structures.

Characterizing Clutter in the Context of Detecting Weak Gaseous Plumes in Hyperspectral Imagery

Sensors, 2006
Weak gaseous plume detection in hyperspectral imagery requires thatbackground clutter consisting of a mixture of components such as water, grass, and asphaltbe well characterized.
