Indian Defence Review Vol 30.2 Apr-Jun 2015 by Col Danvir Singh,Brig Gurmeet Kanwal,Air Marshal Dhiraj Kukreja,Air Marshal Anil Chopra,Vice Adm DSP Verma,Claude Arpi Pdf

Two issues that dominated the debates of the strategic community in the first quarter of this year were; ‘Make in India’ energetically marketed at the Aero-India Show and the Defence Budget. The Defence Budget is looked at intently to get the general emphasis of the government on security. Brig Gurmeet Kanwal has debated this lucidly. Maintaining a large standing armed force requires more than mere day-to-day support. An ill-equipped large force mired with equipment hollowness is not a guarantee for security but in a future war will be cannon fodder for the adversary. Someone will have to be held accountable to the nation for this debilitating lapse. Or take a conscious decision to reduce its size if this country cannot afford a well equipped large armed force!!! Preparing an armed force on a long-term basis requires a deeply considered perspective of its future role in the national security scheme and the road map for its implementation. The absence of a doctrine and the hesitation of establishing a single point of contact on all matters military have been well debated in this issue. Generals Harwant and Banerjee and Colonel Achutan look at the aspects of doctrine. ‘Make in India’ has been the didactic theme of this Government. It needs to be spelt out in clear terms and not left to the (mis-)interpretation of the bureaucracy. Make in India will be feasible only when the basic industrial manufacturing has notched up a number of counts and the manpower skills to go with it are matching. Currently it is more theoretical than implementable. The articles Dr Misra, Air Marshal Kukreja and Group Captain Noronha address these issues with particular reference to the aero-space industry. Two articles relate to the major current event on PM Modi’s visit to China; the first is on Tibet and the second on the boundary issue. Cyber space is emerging the next frontier; Gen Davinder Kumar has generated an excellent discussion on the issue. Col Harjeet has looked at the implications of social media on security. As a first Claude Arpi has documented a diary highlighting prominent issues relating to China’s PLA in this first quarter. This will now be a regular feature in the print edition. Wishing all our readers a worthwhile professionally invigorating reading experience.

Principles of Sonar Performance Modelling by Michael Ainslie Pdf

Sonar performance modelling (SPM) is concerned with the prediction of quantitative measures of sonar performance, such as probability of detection. It is a multi-disciplinary subject, requiring knowledge and expertise in the disparate fields of underwater acoustics, acoustical oceanography, sonar signal processing and statistical detection theory. No books have been published on this subject, however, since the 3rd edition of Urick’s classic work 25 years ago and so Dr Ainslie’s book will fill a much-needed gap in the market. Currently, up-to-date information can only be found, in different forms and often with conflicting information, in various journals, conference and textbook publications. Dr Michael Ainslie is eminently qualified to write this unique book. He has worked on sonar performance modeling problems since 1983. He has written many peer reviewed research articles and conference papers related to sonar performance modeling, making contributions in the fields of sound propagation and detection theory.

Ocean Ambient Noise by William M. Carey,Richard B. Evans Pdf

This monograph develops the theory of noise mechanisms and measurements, and describes general noise characteristics and computational methods. The vast ambient noise literature is concisely summarized using theory combined with key representative results. The air sea boundary interaction zone is described in terms of nondimensional variables requisite for future experiments. Noise field coherency, rare directional measurements, and unique basin scale computations and methods are presented. The use of satellite measurements in these basin scale models is demonstrated. A series of appendices provides in-depth mathematical treatments which will be of interest to graduate students and active researchers.

Underwater Acoustics by Richard P. Hodges Pdf

Offering complete and comprehensive coverage of modern sonar spectrum system analysis, Underwater Acoustics: Analysis, Design and Performance of Sonar provides a state-of-the-art introduction to the subject and has been carefully structured to offer a much-needed update to the classic text by Urick. Expanded to included computational approaches to the topic, this book treads the line between the highly theoretical and mathematical texts and the more populist, non-mathematical books that characterize the existing literature in the field. The author compares and contrasts different techniques for sonar design, analysis and performance prediction and includes key experimental and theoretical results, pointing the reader towards further detail with extensive references. Practitioners in the field of sonar design, analysis and performance prediction as well as graduate students and researchers will appreciate this new reference as an invaluable and timely contribution to the field. Chapters include the sonar equation, radiated, self and ambient noise, active sonar sources, transmission loss, reverberation, transducers, active target strength, statistical detection theory, false alarms, contacts and targets, variability and uncertainty, modelling detections and tactical decision aids, cumulative probability of detection, tracking target motion analysis and localization, and design and evaluation of sonars

Wireless Sensor Networks by Yen Kheng Tan,Geoff Merrett Pdf

Over the past decade, there has been a prolific increase in the research, development and commercialisation of Wireless Sensor Networks (WSNs) and their associated technologies. WSNs have found application in a vast range of different domains, scenarios and disciplines. These have included healthcare, defence and security, environmental monitoring and building/structural health monitoring. However, as a result of the broad array of pertinent applications, WSN researchers have also realised the application specificity of the domain; it is incredibly difficult, if not impossible, to find an application-independent solution to most WSN problems. Hence, research into WSNs dictates the adoption of an application-centric design process. This book is not intended to be a comprehensive review of all WSN applications and deployments to date. Instead, it is a collection of state-of-the-art research papers discussing current applications and deployment experiences, but also the communication and data processing technologies that are fundamental in further developing solutions to applications. Whilst a common foundation is retained through all chapters, this book contains a broad array of often differing interpretations, configurations and limitations of WSNs, and this highlights the diversity of this ever-changing research area. The chapters have been categorised into three distinct sections: applications and case studies, communication and networking, and information and data processing. The readership of this book is intended to be postgraduate/postdoctoral researchers and professional engineers, though some of the chapters may be of relevance to interested masters level students.
