Radar Communication Overview

Radar communication document summarizes in 3 sentences: Radar works by emitting electromagnetic waves that bounce off targets and return to the radar, allowing it to detect and locate targets based on the round-trip travel time. It has wide applications including military target detection, air traffic control, weather monitoring and law enforcement. The history of radar development is traced from early experiments in the late 19th century through key advances that enabled its widespread use in World War II and beyond.

RANGING
R=c*Tp/2 (meters)

Where,

R = range to target(meters)

Tp = round-trip propagation

time(seconds) c = the

propagation velocity(m/s)
