Role of ELECTRONICS in Defense

As days go by, the role of electronics in Defense systems becomes more and more important also the advancement which come in it. This is because of the growing application of sophisticated electronic technology in Defense equipment...

Defense Research and Development Organization (DRDO) has developed a large number of electronic materials, devices and components that have helped the country in achieving self-reliance to a considerable extent in Defense electronics. These developments have resulted to enhance the strength of our Armed Force.

Bharat Electronics Limited (BEL), is the premier defense electronics company in India. From the initial production of Transceivers for Indian Army’s radio communication equipment , including high-tech products such as radars, sonars, communication equipment, electronic warfare equipment, opto-electronics, tank electronics, and components.

Electronic devices and components by DRDO:

1) 12 GHz MMIC Technology

Microwave monolithic integrated circuits (MMICs) are increasingly being used in microwave systems. The main aim of MMIC is to reduce weight and size of the systems and increase the speed of signal processing. A variety of MMIC circuits are used in radar communication and missile guidance for several applications.

2) MM Wave Communication

DRDO has developed a few MMW communication systems at Ka-band, V-band, and W-band, covering a maximum range up to 20 km with clear LOS under severe radio interference environment. The system can be used for point-to-point communication up to 120 voice channels.

3) MMW Components for Radar & Communication

Several leading edge technologies have been developed and exploited to realize operational systems. For example, high power solid-state transmitters have been realized using resonance cavity power and hybrid power combining techniques at 35 GHz and 94 GHz.

4) MMW Sensor for Top Attack

The sensor has been fabricated using planar waveguide circuits and MMW components into a single compact, rugged plate capable to withstand the firing shock of 10000 g.

5) Ground Mine

The processor-based ground mine (PBGM) is a microprocessor- controlled advanced mine to be laid either by a surface ship or launched from a submarine. It is classified as an intelligent mine as it can assess and quantify the environment and accurately identify and destroy actual targets. The mine is designed to detonate using any one or a combination of the three influences created by a target.

Recently BEL is handed over the Artillery Combat and Control Systems, which it had developed in association with DRDO to the Indian Army. Some other products that were executed recently include :

• High Power High Frequency (HF) Communication Sets
• Frequency Hopping Very High Frequency (VHF) Trans receivers
• Ultra High Frequency ( UHF) Handheld Radio
• UHF Radio Relays, Upgraded Fire Control Systems
• Ship borne and Airborne Electronic Warfare Systems

The company is decided to increase its product profile and turnover in the coming years. The company has in fact drawn an ambitious plan to double its present turnover to 100 billion by 2014-15. Under this plan, the major segments that would contribute in increasing revenue are radar, communications and electronics warfare. To achieve the target, it has set up Development and Engineering teams to work closely with the armed forces for certain major projects.

Conclusion:

The Indian defense system have lots of manpower but also not able to produce the things which compete the other countries, the major problems that Indian defense system is facing is the lack of latest technology, & moreover the projects which requires lot to time to implement. To overcome this Indian government has to be somewhat strict in making the laws for that.These were my views. What are your views and information on the same.
