By transmitting radio frequency signals and analyzing the reflected echoes, radar systems can determine the distance, direction and velocity of a target. A radar antenna emits short pulses of ๐๐ฅ๐๐๐ญ๐ซ๐จ๐ฆ๐๐ ๐ง๐๐ญ๐ข๐ ๐ฐ๐๐ฏ๐๐ฌ that travel at the speed of light. When these waves encounter an object such as an aircraft, vehicle or weather formation a portion of the energy is reflected back to the receiver. By measuring the time delay between the transmitted pulse and the returned echo, the radar system calculates the targetโs range using:
๐๐ข๐ฌ๐ญ๐๐ง๐๐ = (๐๐ฉ๐๐๐ ๐จ๐ ๐๐ข๐ ๐ก๐ญ ร ๐๐ข๐ฆ๐ ๐๐๐ฅ๐๐ฒ) / ๐
Modern radar systems incorporate advanced signal processing to improve detection accuracy. Through the ๐๐จ๐ฉ๐ฉ๐ฅ๐๐ซ ๐๐๐๐๐๐ญ, they can estimate the velocity of moving targets by analyzing frequency shifts in the reflected signal. Directional antennas and beam steering techniques further enable precise determination of a targetโs angular position. Operating across ๐๐ซ๐๐ช๐ฎ๐๐ง๐๐ฒ ๐๐๐ง๐๐ฌ ๐ซ๐๐ง๐ ๐ข๐ง๐ ๐๐ซ๐จ๐ฆ ๐๐๐
