The Centre for Electromagentics (CEM) of CSIR-NAL, Bangalore has been working on Stealth Technologies also known as Low Observable technology, in line with country’s goal of self-realization in the strategic sector. The objective of low observable technology is to enhance the survivability of defense vehicles by reducing radar cross section (RCS). The RCS reduction covers a range of techniques used in different platforms such as aircraft, ship, submarine, missile and satellite to make them less detectable (ideally invisible) to enemy radars. These techniques are shaping, usage of radar absorbing materials and structures (RAM/RAS), implementation of passive and active techniques such as probe suppression, active RCS reduction, and plasma-based RCS reduction. An illustrative brief overview of work done in the area of RCS estimation and control, Active RCS reduction in phased arrays, low RCS antennas, and radar absorbing structures (RAS) would be presented.

Biography:

Dr. Hema Singh is working as Chief Scientist in Centre for Electromagnetics, National
Aerospace Laboratories (CSIR-NAL), Bangalore, India. She is also holding a position of
Professor of the AcSIR academy in the Faculty of Engineering Sciences.
She received Ph.D. degree in Electronics Engineering from IIT-BHU, Varanasi India in
Feb. 2000. Her PhD was on RCS studies. Since then, she has been contributing
extensively in this highly specialized field. She has also worked in academic institutes
such as BITS, Pilani (Rajasthan), and Govt. PG College, Kashipur (Uttarakhand). She has
joined CSIR-NAL as Scientist in January 2005.
Dr. Singh has total of 24 years of work experience in academic and R&D organizations.
She is one of the experts in the field of Radar Cross Section estimation and control,
available in India. It is not an exaggeration to state that Dr. Singh is the only Indian
researcher working in the field of RCS estimation of phased antenna arrays and active
RCS reduction.
Her focus area of research is indigenous development of stealth technology based on
Radar Cross Section (RCS) estimation and control, Radar Absorbing Structures (RAS),
low RCS phased arrays, and Active RCS reduction, which is one of the critical challenges
in the country’s self-reliance in strategic sector. Other contributions of Dr. Singh include
EM analysis of propagation in an indoor environment for Boeing USA, low RCS
electronic warfare antennas, RCS estimation of electrically large structures, radomes, and
THz technologies for high speed 5G/6G communication systems.
She has authored 15 books (Cambridge Univ. Press, Springer, Taylor & Francis), 5 book
chapters, 1 patent, 7 software copyrights, and around 520 research publications.
She has been awarded IEEE Professional Excellence Award for Women in Engineering
(2024). She has also received IEEE Women Technologist of Year 2020 by IEEE
Bangalore chapter. She also got IETE-Smt Ranjana Pal Memorial Award-2018 in the
novel area of Active RCS reduction, by indigenously developing an efficient adaptive
algorithm. She was awarded Best Woman Scientist in CSIR-NAL in 2008. She is a
Fellow of Aeronautical Society of India and Senior IEEE member. She has been Asia
representative in IEEE-Industry Initiative Committee (2012-2015).
She has been actively involved in various sponsored and grant-in-aid projects of defence
sector (DRDO) and international collaborative projects (Boeing USA). She has been
continuously guiding and training graduate and post-graduate students from Science and
Engineering background.
