it is worth noting, drdo has been doing work on this.MCA is supposed to be stealth , but india doesn't have any experience with RAM , any idea where we plan to get that tech from?
http://www.bharat-rakshak.com/MISSILES/ballistic/prithvi.htmlAnother defence the missile has, is the application of a special type of radar absorbing paint to reduce radar signature.
that is with reference to prithvi missile which can be replicated on to MCA too.
i was browsing and found this which is very old but very interesting -

NASHIK, December 31: The Defence Research and Development Organisation (DRDO) and the Indian Air Force (IAF) jointly experimenting with the development of a Stealth aircraft, have achieved 94 per cent of radar invisibility.
According to Squadron Leader K P Gawd (from 7 Base Repair Dept, Air Force Station, Tughlakabad), who presented a paper on "Steps towards fabrication of an invisible aircraft" at the 13th National Convention of Aerospace Engineers held at the Hindustan Aeronautics Ltd (HAL) complex at Ojhar, a breakthrough had been achieved during experiments involving two scale models of an aircraft. According to Squadron Leader Gewd, Time Domain and Frequency Domain methods were used in addition to the two antenna method to determine radar invisibility and a 94 per cent invisibility was achieved. Efforts are being made to reduce the Radar Cross Section (RCS) signature of the aircraft to reduce detection by an enemy radar. The process is to coat an object with radar absorbing materials, which absorb energy from electromagnetic fields passing through them. Such materials have complex indices of refraction, which include magnetic and electric effects. There are two kinds of such materials-narrow band absorbers and broad bad absorbers. Besides, body shaping, impedance leading and chiroshield play a crucial role in fabricating an invisible aircraft. The DRDO and the IAF used an absorber having electromagnetic properties in KU band, following the two antenna method (spectrum Analyser) the time domain method and the frequency domain method. The drawbacks experienced were the RCS isolation error and the frequency response error. The former was caused by leakage between the antenna while the latter by non ideal frequency response of the cables, connectors, couplers and antennas. The errors were subsequently rectified and zero reflection for all frequencies achieved.
The development of an invisible aircraft is being done on the lines of the B 2 Stealth Bomber of the United States Air Force. Experts believe thatit is possible to make retroreflectors such as ship and submarines invisible to sonars.

besides india has composites technology which is part of LCA and also HAL manufactured SU 30MKI's will have more composites built in them. india infact will be contributing to PAKFA on this.
so india has tech. besides FGFA experience will also contribute in terms of RAM, i guess.
