What is Radar?
Radar is an incredibly powerful tool for performing object detection and location for a variety of applications. Radar, which is an acronym for radio detection and ranging, uses electromagnetic waves (EW) within the radio frequency (RF) spectrum to detect, locate, track, and identify objects of interest on the ground or in the air over long ranges. At the most basic level, the EW signal is transmitted into the environment and the radar “listens” for a return signal, or echo. A return signal is generated when an object is in the path of the original signal, causing a reflected signal that bounces back to the receiver. It is often assumed that the object commonly referred to as a target, must be metal to reflect a radar signal, but it can be constructed of almost any type of material sufficiently different than the air that the radio wave is propagating through (plastic, rubber, glass, metal, wood, etc.). The time between the transmission of the original signal and reception of the return signal, which is known as time of flight, provides a significant amount of information about the detected object, including its location, distance, velocity, and characteristically unique features of motion which can be used to classify a target.
Calculating "Curvature" of the Earth.
IT'S FLAT. THERE IS NO CURVATURE!

In 2022, I had a conversation with a 28 yo Navy soldier. He said that he was trained in all surface to air weapons on his ship. He said that they had targets miles away and in their calculations never included the curvature or the rotation of the earth at 1040mph but always assumed a flat nonrotating earth like the manual said.
He was indeed a Flat Earther!
