Active safety vehicle devices are getting more attention recently. To prevent traffic accidents, the environment in front and even around the vehicle must be checked and monitored. In the present applications, mainly camera and radar based systems are used as sensing devices. Laser scanner, one of the sensing devices, has the advantage of obtaining accurate measurement of the distance and the g...

This article describes an investigation of the new possibilities offered by SAR altimetry compared with conventional altimetry in the detection and characterization of non-ocean targets. We explore the capabilities of the first SAR altimeter installed on the European Space Agency satellite CryoSat-2 for the detection and characterization of ships. We propose a methodology for the detection of a...

The Tevatron at Fermilab is at present the world’s highest energy particle accelerator. After extensive refurbishments, data taking for Run II started in 2001, and by the end of 2003 over 200 pb of usable integrated luminosity had been accumulated by each Collider experiment, double the total for Run I. In preparation for Run II, the CDF detector also underwent an extensive upgrade. Of special ...

Air-to-sea surveillance and tracking systems that provide rapid and positive identification of Non-Cooperative and Stealthy Targets (NCSTs) are connected with Inverse Synthetic Aperture Radar (ISAR) concepts and techniques. ISAR has several shortcomings that could be dealt with the contribution of a Phase Comparison Monopulse system. This paper presents the possible output for the height dimens...

A radar system is generally implemented and addressed to detect the target of concern. So, in a radar system, analysis and application of Ultra Wide Band (UWB) signals solves most of the problems of radar target detection. Since multiple-input multiple-output (MIMO) radar possess significant potentials for fading mitigation, resolution enhancement and interference and jamming suppression, by op...

Bistatic radar target tracking is challenging due to the fact that measurements are nonlinear functions of Cartesian state. The converted measurement Kalman filter (CMKF) converts raw into coordinates prior and superior extended for certain problems. challenges CMKF debiasing approximating error covariance. Due no closed form biases, we utilize second-order Taylor series expansion conventional ...

In the last decade, significant progress has been made on developing automatic farfield tracking systems. The PETS 2007 dataset provides some interesting event detection challenges. In this paper, we describe a method of bootstrapping a background model in the presence of significant lighting changes. We then use a blob tracker as an attention mechanism for finding tracks of interest, which we ...
