A technology demonstrator for active RCS reduction systems will be developed by NAL in collaboration with

A technology demonstrator for Active Radar Cross Section (RCS) Reduction Systems is being developed by National Aerospace Laboratories (NAL) in partnership with industry partners. Enhancing stealth capabilities in aerospace applications, especially for military aircraft, is the goal of this initiative.

By using sophisticated techniques to reduce an object’s radar visibility, active RCS reduction makes it more difficult for adversary radar systems to detect and track.

This method effectively cancels out the reflected signals by using antennas to emit signals that interfere with incoming radar waves. Phased array technology and digital radio-frequency memory (DRFM) can be used by systems to analyze and produce the signals required for efficient cancellation.

Instead of reflecting radar waves, these materials are made to absorb them. NAL has created a number of RAM products, such as flexible coatings and sheets that can be used on aircraft surfaces to drastically lower radar signatures in a variety of frequency ranges.

In order to accomplish both passive and active RCS reduction, recent developments have concentrated on employing meta-surfaces, which are engineered materials that control electromagnetic waves. Radar signals can cause these surfaces to dynamically modify their characteristics, increasing their efficacy across a wider bandwidth.

NAL’s cooperation with business partners is a component of India’s larger plan to improve its defense capabilities by developing domestic technology.

To demonstrate the efficacy of active RCS reduction techniques on legacy aircraft, NAL is developing technology demonstrators. According to preliminary testing, employing specially created coatings and structures significantly lowers radar signatures.

Achieving the intended RCS reduction results requires the development of sophisticated materials, such as paints that absorb radar and structures made of magnetic flakes. Based on particular operational requirements, these materials are designed to maximize absorption characteristics.

In order to facilitate integration without requiring significant alterations to current platforms, the new technologies are being developed to be compatible with existing aircraft systems.

India’s defense capabilities will be significantly impacted if active RCS reduction technologies are successfully implemented. India hopes to increase its operational efficacy and strategic deterrence in contested environments by improving the stealth characteristics of its aircraft.

In order to develop more capable and resilient military platforms, the aerospace industry is increasingly combining advanced materials science and electronic engineering, as this collaboration demonstrates. As these technologies advance, India will probably be positioned as a competitive force in the global aerospace market, able to support international defense cooperation in addition to meeting domestic demands.
