anomalous propagation การใช้

• Anomalous propagation can be a limiting factor for the propagation of radiowaves, especially the super refraction.
• Anomalous Propagation is different from " ground chaff, sand storms, volcanic eruption plumes, and other non-precipitation meteorological phenomena.
• Erieye detects and tracks air and sea targets out to the horizon, and sometimes beyond this due to anomalous propagation  instrumented range has been measured at.
• The facility was established in 1961 to conduct research on very high frequency and microwave antenna systems specifically, on problems associated with anomalous propagation in communications interception.
• Clutter may also originate from multipath echoes from valid targets caused by ground reflection, atmospheric ducting or ionospheric reflection / refraction ( e . g ., anomalous propagation ).
• Temperature inversion and anomalous propagation can occur at most latitudes but they are more common in tropical climates than temperate climates, usually associated with high pressure areas ( anticyclones ).
• Clutter may also originate from multipath echoes from valid targets caused by ground reflection, atmospheric ducting or ionospheric reflection / refraction ( e . g ., Anomalous propagation ).
• Other ways anomalous propagation is recorded is by troposcatters causing irregularities in the troposphere, scattering due to meteors, refraction in the ionized regions and layers of the ionosphere, and reflection from the ionosphere.
• Based on the information available, the Committee's researcher ( Thayer ) felt that while anomalous propagation was possible, the lack of other targets on radar scopes at the time made it unlikely.
• It faded from the scope as it passed over the base ( possibly suggesting anomalous propagation as a source for the target, although ground-based radars almost always have a blind spot overhead ), reappearing to the west.
