Book excerpt: The growing energy needs have eventually increased the development of wind turbines. The constructions of wind turbines have several potential impacts of which the most significant factor is the increasing bird mortality rates due to collision and habitat loss. Since then, radars have been deployed to study the behavior of birds towards wind turbines. Radars employ target tracking for identifying the targets (birds) accurately and efficiently. Several methods of tracking were developed to improve the tracking efficiency of the radars over the years. Most widely used tracking techniques are Kalman filter and particle filter. These filters use data with random errors and estimate accurate values for the current state of the system. Kalman filter is a linear estimator which does not depend on a set of past observations and hence efficient in real time applications. The particle filter also known as sequential Monte Carlo method is a nonlinear estimator which uses a set of particles with various weights for estimation. However, particle filters have high computation time. Kalman and particle filters were developed over the years creating various models for various types of systems. A block version of Compressive Matching Pursuit (CoSaMP) algorithm used in signal reconstruction called BCoSaMP was employed in tracking. It was seen to give a similar or better performance than particle filter with less computation time. The BCoSaMP algorithm with Kalman filter estimation was developed which reduces the mean square error as compared to other models in certain cases. This thesis focuses on developing tracker models in radR. Kalman filter tracking model based on linear data and Gaussian noise that operates over a variety of target motions and velocities is developed. Particle filter is designed for nonlinear target motion with non-Gaussian noise. BCoSaMP model that assumes data as sparse is applied for target tracking and a modified BCoSaMP which replaces least square estimation with Kalman filter estimation are also implemented. These models were tested with different data sets and a comparative analysis is performed. The algorithms are tested on simulated data and marine radar data in radR to compare the effects of the developed tracker models with the conventional methods in radR. The hybrid algorithm is shown to have better performance over the other models in the case of simulated track for some targets. Particle filter has the highest detection rate with marine radar data.

Download or read book Target Detection by Marine Radar written by John N. Briggs and published by IET. This book was released on 2004-12-03 with total page 702 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radar is a legal necessity for the safe navigation of merchant ships, and within vessel traffic services is indispensable to the operation of major ports and harbours. Target Detection by Marine Radar concentrates solely on civil marine operations and explains how marine surveillance radars detect their targets. The book is fully illustrated and contains worked examples to help the reader understand the principles underlying radar operation and to quantify the importance of factors such as the technical features of specific equipment, the weather, target reflection properties, and the ability of the operator. The precision with which targets are positioned on the radar screen and with which their progress is tracked or predicted depends on how definitely they have been detected, therefore a whole chapter has been devoted to the issue of accuracy. The various international regulations governing marine radar are examined, a brief historical background is given to modern day practice and the book doses with a discussion of the ways in which marine radar may develop to meet future challenges.

Download or read book Innovative Target Tracking Techniques for Modern Radar and Sonar Systems written by Alfonso Farina and published by Mdpi AG. This book was released on 2023-01-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this Special Issue is to gather recent advances and development in target tracking techniques to determine how they can be adapted for modern radar and sonar systems. After peer review, 17 articles in related areas have been accepted for publishing in this Special Issue. The published articles cover a range of topics and applications central to target tracking. There are eight papers about general multi-target tracking, including the topics of joint tracking and classification [3], adaptive estimation using clutter measurement probability [6], joint localization and tracking [7], extended target tracking [8], tracking with smoothing [11], DOA tracking [12], tracking under low detection probability [14], and sonar tracking and interception [17]. Three papers address multi-sensor multi-target tracking methods. Specifically, a multi-target estimating method for pulsed radar systems is proposed in [2], a joint dwell time and bandwidth optimization method in a radar network is proposed in [4], a and multiple marine ship tracking method with unknown backgrounds is presented in [9]. There are 2 papers [10,15] on the problem of target assignment in multi-sensor multi-target tracking. Moreover, Mallick et al. considered measures of nonlinearity of a polynomial curve in two dimensions [1], Zhao et al. explored the use of calibration targets for which the positions are known to the MPR system, to counter the loss in target localization accuracy arising from transmitter/receiver position errors [13], and Li et al. proposed an algorithm to apply the frequency diversity technique to passive azimuth estimation in [16].

This book was released on 2013 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of wind turbines has increased with growing energy needs. Birds mortality rate is the most significant potential impact occurred due to the construction of wind turbines. Since then, radars have been deployed to study the behavior of birds towards wind turbines. Target tracking using radars has been used in order to detect targets (birds). Deployment of commercially available radars was not an option due to budget limitations. Therefore, this project was developed using marine radar and an open source software called radR and generate results comparable to commercially available radar systems. Generally two kinds of studies are conducted, pre deployment and post deployment of wind turbines. In this thesis pre deployment study over Lake Erie has been done. The primary goal of this study was to collect information on the migration characteristics of nocturnally migrating birds, during the Fall and Spring migration period. Specifically, the objective of this study was to collect baseline information on migration characteristics (i.e., flight direction, migration passage rates, and flight altitudes) of nocturnally migrating birds. This thesis also focuses on developing IMM algorithm for radR. The algorithm is tested on simulated data and real time data in radR to compare effects of the developed tracker models with the conventional methods in radR. The current tracker models in radR have maximum detection rates with equal false alarm rates. The new tracker model was implemented to reduce these error rates in the data processing.

Available in PDF, EPUB and Kindle. Book excerpt: The Special Issue “Radar and Sonar Imaging Processing” is a collection of 21 articles exploring many topics related to remote sensing with radar and sonar sensors. In this editorial, we present short introductions of the published articles. The series of articles in this SI deal with a broad profile of aspects of the use of radar and sonar images in line with the latest scientific trends while making use of the latest developments in science, including artificial intelligence. It can be said that both radar and sonar imaging and processing still remain a “hot topic” and much research in this area is being conducted worldwide. New techniques and methods for extracting information from radar and sonar sensors and data have been proposed and verified. Some of these will stimulate further research while others have reached maturity and can be considered for industrial implementation and development.
