This paper presents a method of imaging a twodimensional section of a walking person using multiple ultrawideband Doppler radar systems. Although each simple radar system consists of only two receivers, different line-of-sight velocities allow target positions to be separated and located. The signal received using each antenna is processed employing time– frequency analysis, which separates tar...

This work deals with the analysis of a multisensor radar system in the context of maritime border control scenario. The system is composed by a receiver that exploits the signal emitted by two non co-operative transmitters of opportunity: a UMTS base station and a FM radio station. An algorithm for selecting the transmitter for the tracking of a radar target is proposed. This algorithm can prov...

This paper proposes a new optimal waveform selection algorithm for intelligent target tracking. In radar systems, optimal waveform is inspired by the improvements in performance. When the target is intelligent and tries to escape from detection, it will maximize the estimation error to degrade the target tracking performance. So the conventional tracking algorithms are not suitable for this sit...

In order to defend the hypersonic glide vehicle (HGV), a cost-effective single-model tracking algorithm using Cubature Kalman filter (CKF) is proposed in this paper based on modified aerodynamic model (MAM) as process equation and radar measurement model as measurement equation. In the existing aerodynamic model, the two control variables attack angle and bank angle cannot be measured by the ex...

Recently, the growing number of inactive Resident Space Objects (RSOs), or space debris, has provoked increased interest in the field of Space Situational Awareness (SSA) and various investigations of new methods for orbital object tracking. In comparison with conventional tracking scenarios, state estimation of an orbiting object entails additional challenges, such as orbit determination and o...

In this paper, we describe an automatic storm tracking system to help with the forecasting of severe storms. The concepts fuzzy point, fuzzy vector, fuzzy length of a fuzzy vector, and fuzzy angle between two non-zero fuzzy vectors are rst examined. We use a region splitting algorithm with dynamic thresholding to determine storm masses in Doppler radar intensity images. We represent the center ...

News Corporation I tall started when Stan Honey (vice president of technology for News Corporation) was taking with David Hill (then-president of Fox Sports, a NewsCorp company). Stan was describing an exciting, emerging technology-virtual electronic billboards-that he felt could benefit Fox Sports. Though impressed with this prospect, David had just acquired the rights to produce National Hock...

Occlusions can degrade object tracking performance in sensor imaging systems. This paper describes a robust approach to object tracking that fuses video frames with RF data in a Bayes-optimal way to overcome occlusion. We fuse data from these heterogeneous sensors, and show how our approach enables tracking when each modality cannot track individually. We provide the mathematical framework for ...

This paper proposes a new radar tracking filter named Noise-estimate Particle Filter (NPF). Kalman filter and particle filter are popular filtering techniques for target tracking. The tracking performance of the Kalman filter severely depends on the setting of several parameters such as system noise and observation noise. However, it is an open problem how to choose proper parameters for variou...
