“…This overcomes the typical limitation of FDA pointed out by other authors (Aziz et al 2007;Singh et al 1997) given by the exponential increase in the number of rules generated to cover a dense target environment. FRA uses the typical input space partitioning by antecedents of rules.…”

“…The output variables in FDA are usually the degree of correlation between observations and tracks, so that the maximum values are searched for as solutions to the association problem. As an alternative to rule-based fuzzy systems, Aziz et al (1999Aziz et al ( , 2007 propose the application of fuzzy clustering means (FCM) algorithm. Their iterative algorithm applies FCM over an active set of measurements and tracks, identifies the pairs with highest membership and removes them to reduce the size of the problem for the next iteration until all measurements are assigned to a track.…”

“…Different proposals range from simple and suboptimal, such as Nearest Neighbor (NN), to other more complex and close to optimal approaches, whose cost is usually excessive when the number of targets and measurements increase, such as Multiple Hypotheses Tracking (MHT), and Joint Probabilistic Data Association Filter (JPDAF). Fuzzy systems have been traditionally applied to data association (Fuzzy Data Association, FDA) with sensor sources such as radar positioning, infrared and Doppler measurements, taking advantage of the flexibility of fuzzy logic to model uncertainty coming from heterogeneous sources and natural ability to handle different types of information (Chen 2000;Han et al 2003;Ermin et al 2000;Gad et al 2002;Aziz et al 1999Aziz et al , 2007. A more detailed analysis of approaches to data association based on this paradigm is presented in the next section.…”

Fuzzy region assignment for visual tracking

In this work we propose a new approach based on fuzzy concepts and heuristic reasoning to deal with the visual data association problem in real time, considering the particular conditions of the visual data segmented from images, and the integration of higher-level information in the tracking process such as trajectory smoothness, consistency of information, and protection against predictable interactions such as overlap/occlusion, etc. The objects' features are estimated from the segmented images using a Bayesian formulation, and the regions assigned to update the tracks are computed through a fuzzy system to integrate all the information. The algorithm is scalable, requiring linear computing resources with respect to the complexity of scenarios, and shows competitive performance with respect to other classical methods in which the number of evaluated alternatives grows exponentially with the number of objects.

“…This can be appreciated by realising that the echo arrives at the receiver at the same instant as the direct signal, independent of the target location, and the Doppler shift of a target crossing the bistatic baseline must be zero, because the transmitter-to-target range changes in an equal and opposite way to the target-to-receiver range, independent of the magnitude and direction of the target velocity. In this case, resolution is totally lost and therefore the observation from this transmitter-receiver pair could hardly degrade the resolution of the whole multistatic radar system [Azi07], [Gre10], [Gre11].…”

SUPPLEMENTARY NOTESGovernment Purpose Rights -University Di Pisa ABSTRACTFor many years, conventional radars transmitted, received, and processed the same waveform on every pulse or burst within a coherent processing interval (CPI), independently of the environment. Now, modern radar systems have considerable flexibility in their modes of operation, both on receive and transmit. In particular, it is possible to modify the waveform on a pulse to pulse basis, and electronically steered phased arrays can quickly point the radar beam in any feasible direction. In the course of this research project, we introduced the Ambiguity Function, an analytical tool for waveform design and analysis that is useful for examining resolution, sidelobe behavior, and ambiguity in range and Doppler of a given signal waveform. Some techniques to design multiple access frequency hop codes with good auto and cross-ambiguity functions are characterized, focusing on the frequency hop patterns. We have shown that the performance of each channel of the multistatic system heavily depends on the transmitted waveform and on the geometry of the scenario, that is, the position of receivers and transmitters with respect to the position of the target. In particular, both geometry factors and transmitted waveforms play an important role in the shape of the Ambiguity Function and hence in the value of the Cramer-Rao Lower Bound (CRLB). We have calculated the bistatic CRLBs of target range and velocity of each transmit-receive pair as a function of the target kinematic parameters and to provide a local measure of the estimation accuracy of these parameters. Finally, in this work we have analyzed the problem of the optimum sensor selection along the trajectory of a tracked ta...

A new GM-PHD filter for multiple emitter targets tracking is proposed in this paper. It integrates the signal features of emitter into the process of weights update. In the case of unknowing the distribution of signal features, the FCM algorithm is used for reference to calculate the correlation coefficients between the measurements and candidate targets in place of the likelihoods. Simulation results show that the proposed method can effectively improve the tracking performance in the scenarios with different clutter densities.
