What is the role of radar in the nuclear missile defense system?

Radar plays a critical role in the nuclear missile defense system. It is an essential tool for detecting, tracking, and intercepting incoming missiles before they can reach their intended targets. Radar is used to provide early warning of a missile launch, track its trajectory, and guide interceptor missiles to their targets. The radar system used in the nuclear missile defense system is a complex network of ground-based and space-based sensors. Ground-based radar systems are used to detect the launch of a missile and track its initial trajectory. These radar systems use radio waves to locate the missile's p....
