Researchers have recently proposed a widely separated multiple-input multiple-output (MIMO) radar using monopulse angle estimation techniques for target tracking. The widely separated antennas provide improved tracking performance by mitigating complex target radar cross-section fades and angle scintillation. An adaptive array is necessary in this paradigm because the direct path from any trans...

The trajectory of a baseball moving through the air is very different from the one we teach in our introductory classes, in which the only force is that due to gravity. In reality, the aerodynamic drag force (which retards the motion) and the Magnus force on a spinning baseball (which causes the ball to curve) play very important roles that are crucial to many of the subtleties of the game. Des...

The authors, in their article, summarize a mixed-models approach applied to the analysis of radar tracking residuals from calibration satellites observed by the Cobra Dane radar. They found that each of the calibration satellites makes its own idiosyncratic contribution to the observed radar tracking residuals. When properly accounted for, these idiosyncrasies increase the statistical power to ...

In the part of radiolocation focused on one target tracking we can find for example active radar and passive surveillance systems but we cannot find any representative of passive radiolocation area. Therefore this paper is focused on the conceptual design and practical solution of passive radar for one target tracking. The scanning of the area of interest is ensured by an antenna system with a ...

A ship detection and tracking algorithm for HF-radar is evaluated by comparison to Automatic Identification System (AIS) and satellite borne Synthetic Aperture Radar (SAR) data to provide an estimate of the detection and false alarm rate performance in a real operational scenario. This paper presents results from the HF-radar experiment that is ongoing since May 2009 and operates two HF-radar s...

In this study, the tracking performance of radar target tracking process by using extended Kalman filter is analyzed. For this purpose, the obtained real radar datasets are used for extraction of the target motion model, observation model, processing noise and measurement noise equations based on experimental study respectively. Extended Kalman filter algorithm is applied to the equations and t...

the radar tracking is one of the best leo satellite tracking methods. while the tracking filters which are mostly linear, and them are not able to have a precise estimation of the objects with nonlinear motion dynamic such as satellite, we should use nonlinear filters. in this paper , firstly, we deal with the problem of the leo satellites motion path modeling according to the satellite motion ...

This paper presents a performance evaluation of nonlinear filtering with Interacting Multiple Model (IMM) algorithm for implementation on Indonesian coastal radar target tracking system. On this radar, target motion is modeled using Cartesian coordinate but target position measurements are provided in polar coordinate (range and azimuth). For this implementation, we investigated two types of no...

Speckle reduction techniques are applied to SAR imagery to produce images that are almost photographic in appearance ("quasi-photographic imagery"). A road tracking system designed for use with photographic imagery has been used to process this data. The road networks extracted from the quasi-photographic imagery are compared with those produced from optical imagery. It was found that the perfo...
