đ°ī¸ Large Phased Array Radar (LPAR) â Explained
A Large Phased Array Radar (LPAR) is a powerful type of radar system that uses phased array technology to detect and track multiple objectsâsuch as missiles, satellites, and aircraftâover long distances with high precision.
đ§ Key Features
Phased Array: Instead of rotating, it uses thousands of tiny antenna elements to steer the radar beam electronically.
Instantaneous Direction Change: Can rapidly switch its focus between targets without physically moving.
High Resolution: Excellent for detecting small or fast-moving objects.
Long Range: Can track targets thousands of kilometers away.
Multifunctional: Used for missile warning, space surveillance, and early warning systems.

đĄī¸ Primary Uses
Missile Defense: Detects and tracks intercontinental ballistic missiles (ICBMs).
Space Surveillance: Tracks satellites and space debris.
Early Warning Systems: Alerts military forces about incoming threats.
National Security: Integral part of NORAD and U.S. Missile Defense Agency infrastructure.
đ How It Works
Radar sends out beams.
Reflecting signals return from objects.
The system processes these returns to detect object position, speed, and trajectory.
