Aircraft Radar Basic Principle
The basic principle used by radar is portrayed in Figure 3.5. The energy radiating from a radar transmitter propagates in a similar fashion to the way ripples spread from an object dropped in water. If the radiated energy strikes an object – such as an aircraft – a small proportion of that energy is reflected [...]
Airborne Radar Systems
Focusing on the airborne radar systems that are the subject of this articles, these cover the frequency range from ~400 MHz to 94 GHz, as shown in Figure 3.3. This illustrates some of the major areas of the spectrum as used by airborne platforms. In ascending order of frequency, typical applications are:
E-2C Hawkeye US Navy [...]
Basic Principles of Radar
The original concept of radar was demonstrated by laboratory experiments carried out by Heinrich Hertz in the 1880s. The term RADAR stands for Radio Aid to Detection And Ranging. Hertz demonstrated that radio waves had the same properties as light (apart from the difference in frequency). He also showed that the radio waves could be [...]
