Context:

The Defence Metallurgical Research Laboratory (DMRL) has made a noteworthy achievement in creating homegrown fused silica radomes for missiles.
Radomes are essential enclosures that safeguard radar antennas and greatly influence the effectiveness of missiles.

About Randomes

A radome is a protective enclosure designed to shield radar or antenna systems from environmental elements while allowing electromagnetic signals to pass through.

Made from rigid materials or air-inflated fabrics, radomes come in various shapes for specific applications.

They maintain antenna performance by mitigating environmental impacts and conceal electronic equipment for security purposes. They prevent rotating antennas from colliding with nearby objects, ensuring durability and efficiency.
