Definition
  1. Noun:
    • A method of detecting and determining the position of distant objects by using radio waves: Radiolocation is a technique that involves transmitting radio waves and analyzing the reflected signals (echoes) to find the location, distance, or speed of objects.
Usage
  • Radiolocation is a key technology in modern navigation and surveillance systems.
  • The term is often used in technical and historical contexts to describe early radar systems.
Examples
  • Noun:
    • The development of radiolocation was crucial for air defense during World War II.
    • Maritime safety relies on advanced radiolocation to track ships in poor visibility.
Advanced Usage
  • "passive radiolocation": A method that detects objects by listening for the radio waves they emit, rather than by sending out a signal and waiting for an echo.
Variants and Related Words
  • Radar (n): A more common and specific system for radiolocation that uses microwave radiation. (Note: While 'radar' is a related technology, it is a specific implementation of the broader concept of radiolocation.)
  • Radio detection and ranging: The full phrase from which the acronym 'radar' is derived; it is essentially synonymous with radiolocation.
Synonyms
  • Radio detection: The process of finding objects via radio waves.
  • Echo ranging: Determining distance by measuring the time for an echo to return.
Related Phrases
  • Radio direction finding (RDF): A related technique for determining the direction of a radio source, which is a component of some radiolocation systems.
Noun
  1. measuring instrument in which the echo of a pulse of microwave radiation is used to detect and locate distant objects
