BEL's software defined radio (SDR) prototype by Aero India 2011

India’s state-run Bharat Electronics Ltd. (BEL) is developing a software-driven radio (SDR) set for India’s armed forces.

Able to function at any frequency, the SDR is lightweight, easy to operate and cost-effective, the company says.

Different radio sets are now being used, depending on very high-frequency, ultra-high-frequency, high-frequency and L-band needs. BEL says the SDR would revolutionize communications on the battlefield.

“We are replacing the hardware with software, which is capable of doing the job effectively. The software could generate waveforms similar to a modulated signal,”
I.V. Sarma, BEL’s director of research and development, tells Aviation Week.

The hardware element will be used only to run the software and to amplify power. BEL hopes to exhibit an SDR prototype during Aero India 2011. A demonstration for the Indian army will follow in March 2011, and airborne and naval variants will follow a year later.

“The army versions will again come in two models — the manpack radio and a handheld one,” a BEL source says. “Only a very few countries in the world have these technologies. The technology gap between these global companies and BEL in developing SDRs is very minimal, as little as six months.”

BEL To Double Investment In R&D

India’s state-run Bharat Electronics Ltd. (BEL) has announced that it will double its investment in research and development (R&D) activities. The company, which until last year invested 4-5% of its turnover in R&D, is expected to devote 8-10% in the next two years.

BEL’s R&D director, I.V. Sarma, told Aviation Week on Nov. 16 that the additional investment would be made available for critical areas like radars, command and control systems, and electro-optics.

“To oversee the R&D activities, we are planning a technology planning division which would map the available resources in the country,” Sarma added.

He said the change in R&D philosophy focuses on three main aspects: identifying the gap in research, identifying and commissioning product development to match the future requirements of clients with an emphasis on meeting international standards, and boosting India’s technology ownership. To this effect, BEL will also develop a technology ownership program.

“This will ensure that new products are developed every three to four years in which the owners will work continuously to develop state-of-the-art technology, irrespective of market demand and product life cycle,” Sarma said. “We want to facilitate development of new products that are available to the customers at the right time. For instance, if the delivery date of a product is 2014, we want to develop it and make it available on the customer’s table by 2013.”

The company will recruit about 450 engineers in the next 18 months, while officials will try to cap the attrition rate at below 5%.

An achievment indeed..........Conratz to Bel on this system .
But i have one concern it would be early to ask but have they made it heck proof.Like hardware is more dificult to heck than software.......... dont u think so.:undecided:

Yes..:agree:

We dont know anything about this..Let things become clear, we will know more about this.
 
I think many new things are coming up in Aero India 2011..
Like Bel's radio and Armed LCH etc....
Wonder wat will HAL bring??
