This book discusses the active and passive radar cross section (RCS) estimation and techniques to examine the low observable aerospace platforms. It begins with the fundamentals of RCS, followed by the dielectric, magnetic and metamaterials parameters of the constituent materials and then explains various methods and the emerging trends followed in this area of study. The RCS estimation of phased array including the mutual coupling effect is also presented in detail in the book. The active RCS reduction is carefully touched upon through the performance of phased arrays, sidelobe cancellers and mitigation of multipath effect. Providing information on various adaptive algorithms like least mean square (LMS), recursive least square (RLS) and weighted least square algorithms, the authors also mention the recent developments in the area of embedded antennas, conformal load bearing antenna, metamaterials and frequency selective surface (FSS) based RCS reduction.
Hema Singh has worked as a Senior Scientist in the Centre for Electromagnetics, CSIR-National Aerospace Laboratories, Bangalore, India since January 2005. She obtained her PhD degree in Electronics Engineering from the Institute of Technology (IT-BHU), Banaras Hindu University, India. Her active areas of research and teaching interests are Computational Electromagnetics for Aerospace Applications and RF and Microwaves. Dr Singh received the Best Woman Scientist Award in CSIR-National Aerospace Laboratories, Bangalore in 2008 for her contribution in the areas of phased antenna array, adaptive arrays and active RCS reduction. Rakesh Mohan Jha is currently working as Chief Scientist and Head, Centre for Electromagnetics, CSIR-National Aerospace Laboratories, Bangalore. He obtained his PhD (Engg.) degree from the Department of Aerospace Engineering at the Indian Institute of Science, Bangalore in 1989 in the area of Computational Electromagnetics for Aerospace Applications. Dr Jha was a SERC (UK) Visiting Post-Doctoral Research Fellow for one year at Oxford University, Department of Engineering Science in 1991. He worked as an Alexander von Humboldt (AvH) Fellow at the Institute for High Frequency Techniques and Electronics, University of Karlsruhe, Germany in 1992-3 and more recently in 2007 on AvH Reinvitation. He was awarded the Sir C. V. Raman Award for Aerospace Engineering for the Year 1999. Dr Jha was elected Fellow of INAE (FNAE) in 2010 for his contributions to the EM Applications to Aerospace Engineering. Dr Jha has published a number of research papers in international journals.
