CSIR-NAL has successfully designed, developed, and validated an innovative 11-layer sandwich radome, incorporating two distinct Frequency Selective Surface (FSS) layers for the Active Electronically Scanned Array (AESA) radar of the Advanced Medium Combat Aircraft (AMCA).
Building on the success of the flat panel prototypes, a full-scale (1:1) truncated 500 mm nose-cone radome was fabricated. Radar Cross Section (RCS) measurements conducted at RCI showed close agreement between measured and simulated results across the EM bandwidth 2–18 GHz range, confirming the robustness of both the electromagnetic design and the fabrication process.
With these milestones achieved, CSIR-NAL is now progressing towards the fabrication of a full-scale 2.2M long operational radome for AMCA—marking a significant advancement in indigenous stealth technology and advanced radar integration, in line with the Self Reliance India.
