The basic principle behind radar is simple - extremely short bursts of radio energy (traveling at the speed of light) are transmitted, reflected off a target and then returned as an echo. Radar makes use of a phenomenon we have all observed, that of the ECHO PRINCIPLE.
Radar Functions • Normal radar functions: 1. range (from pulse delay) 2. velocity (from Doppler frequency shift) 3. angular direction (from antenna pointing) • Signature analysis and inverse scattering: 4. target size (from magnitude of return) 5. target shape and components (return as a function of direction) 6. moving parts (modulation of ...
1 Basic radar principles. 1.1 Introduction. The word RADAR is an acronym derived from the words Radio Detection and Ranging. In the United Kingdom it was initially referred to as radio direction finding (RDF) in order to preserve the secrecy of its ranging capability.
Topics reviewed include the vertical structure of the atmosphere, the radio refractive index and its fluctuations, the radar equation (a relation between transmitted and received power), radar...
Principles of Modern Radar: Basic Principles is a comprehensive and modern textbook for courses in radar systems and technology at the college senior and graduate student level; a professional training textbook for formal in-house courses for new hires; a reference for ongoing study following a radar short course; and a self-study and professional reference book.
From a conceptual point of view, the operating principle of a radar system can be summarized as follows: • the radar radiates electromagnetic waves using a transmit antenna; • the radiated energy propagates in space and hits the objects contained in the sur-rounding environment;
Introduction to Dual Polarization Weather Radar. An interdisciplinary and easy-to-understand introduction to the subject, covering fundamental theory and practical applications supported by numerous operational examples.
