MESSAGE FROM THE COMMANDING OFFICER

1. Indian Navy’s recent acquisitions like Vikramaditya, Kolkata,
Kamorta, Arihant, NOPVs as well as Mid Life Upgrade programme of
existing platforms have brought in a plethora of new technologies. The
upkeep and maintenance of these new inductions is a challenge. To meet
the challenge the training curriculum at Valsura must adapt and
continuously keep pace with the changing technologies and systems.
Correct training, correct training inputs and correct grooming alone
enhances the Fleet output. A forum like JEEE gives an excellent
opportunity for exchange of ideas, field experiences and technical know-
how, to guide the present and future generation of Electrical Officers and
Sailors.

2. It is a challenge to stay abreast of the latest developments and
technologies specially in the field of Weapons and Sensors. With the Navy
poised for a continuous growth, newer and newer technologies would have
to be assimilated by the officers and men. This alone can ensure that the
Indian Navy is agile, capable and operationally ready at all times to ensure
secure seas for a resurgent nation. JEEE, is therefore an attempt to bridge
the gap, and educate not only the personnel of Electrical branch, but the
Navy at large.

FROM THE CHIEF EDITOR’S DESK

1. Journal of Electrical and Electronics Engineering is heralding into
third year of its publication. The response, it has garnered since inception
is overwhelming. While Technology evolves and follows Moore’s Law, we
must be able to adapt and change with it, to stay current and relevant. With
this dynamics in mind, this year we have evolved JEEE into four sections
including industry perspective with contributions from defence industry.

2. With the commissioning of new platforms, Navy has inducted state
of art technologies in the fields of sensors, weapons and power generation.
While formal training stops the day an officer or a sailor completes his
training at Valsura, JEEE gives the alma matter an opportunity to beckon
those, who have passed through her portals, post their ab-initio and
professional training. With disambiguation in mind, a dedicated section on
Back to Basics (B2B) has been included. JEEE gives Valsura an
opportunity to disseminate theoretical as well as technological concepts to
entire Naval fraternity. Often misunderstood topic on Alignment has been
selected this year, to give a glimpse of theory behind it and how it is
undertaken onboard for benefit of our readers. Topics on Techniques of
Direction Estimation and Measurement of Receiver Sensitivity of Electronic
Support Measure (ESM) Systems to ensure Optimum Performance and
Realising Microwave Frequencies using Frequency Synthesisers have
been included to keep readers synchronised with the latest developments
in the fields of Electronics Warfare and Direct Digital Synthesisiers.

3. A dedicated section on Technologies has been included to keep our
readers current with evolving technologies and new systems being
inducted into Navy.

4. As an organisation, we must learn from the experiences of the
people in the Fleet, Trial Teams and Yards. Since JEEE’s main aim is
exchange of ideas and field experiences, I am thankful to the contributors
from the field units for their painstaking research and efforts in collating the
articles for the field experience section.

5. Indian Navy has witnessed unprecedented expansion with
preponderant shift towards the paradigm of indigenisation in last decade.
Infact, since release of last issue of JEEE, several new platforms have
been commissioned into the Indian Navy. With Honourable PM himself

advocating “Make in India” policy, to transform India into a global
manufacturing hub and government permitting upto 49% FDI in defence
manufacturing, we have evolved JEEE into a forum for domestic defence
industry to interact with the end users. A section completely dedicated to
industry and by industry, has been included for the first time.

6. It was really heartwarming to see volumes of contributions and due
to paucity of space, we could not publish all of them. The Editorial Board
appreciates the time and effort devoted by contributors and would like to
thank them all. As always, suggestions and criticisms towards improving
JEEE further are welcome. We are confident that JEEE will continue to
grow and carve an unparalleled niche for itself in times to come.
