CHAPTER 1 — BASIC RADAR PRINCIPLES AND GENERAL …
1 CHAPTER 1 BASIC RADAR PRINCIPLES AND GENERAL CHARACTERISTICSINTRODUCTIONThe word RADAR is an acronym derived from the phraseRAdioDetectionAndRanging and applies to electronic equipment designed for detecting andtracking objects (targets) at considerable distances. The BASIC principlebehind RADAR is simple - extremely short bursts of radio energy (traveling atthe speed of light) are transmitted, reflected off a target and then returned asan makes use of a phenomenon we have all observed, that of theECHO PRINCIPLE. To illustrate this principle, if a ship s whistle weresounded in the middle of the ocean, the sound waves would dissipate theirenergy as they traveled outward and at some point would disappear , however the whistle sounded near an object such as a cliff some of theradiated sound waves would be reflected back to the ship as an form of electromagnetic sig
extremely short burst of radio-frequency (r-f) energy to travel to the target ... These low frequency radar signals are subject to several limitations, but despite the drawbacks, VHF represented the frontier of radar ... emitted in pulses of electromagnetic energy in the radio-frequency band 3,000 to 10,000 MHz used for shipborne navigational ...
