A military radar is a system used by the military to detect and track aircraft, missiles, ships, and other objects in the air or on the ground. It uses radio waves to determine the range, angle, and velocity of the objects it detects. Military radars are an essential tool for surveillance, early warning, and air defense, providing crucial information for military operations and national security. They can be deployed on land, at sea, or in the air, and are designed to operate in various environmental conditions and combat scenarios. **

Additionally, some military aircraft may not be visible on public flight radars at all, especially during sensitive operations or exercises. **
