Tropospheric scatter - Wikipedia
WebTropospheric scatter, also known as troposcatter, is a method of communicating with microwave radio signals over considerable distances – often up to 500 kilometres (310 mi) and further depending on frequency of operation, equipment type, terrain, and …
Radio Propagation by Tropospheric Scattering - Bob Atkins
WebCommunication is only possible when the moon is visible to both stations. Of all the possible propagation modes, only tropospheric scatter (troposcatter) provides a reliable and predictable mode of operation for working DX on the VHF/UHF/microwave bands on a day-in, day-out basis using moderate equipment.
WebThe NBS Technical Notes provide detailed methods for predicting forward scatter attenuation in the form of data and equations involving elementary functions; evidently, the equations are based on curve fitting. There is scant information on how these data are related to fundamental tropospheric scatter theory.
Beyond-Line-Of-Sight Troposcatter Communications Primer
WebJuly 16th, 2020 - By: Kasyap Patel. Though tropospheric scatter (troposcatter, or tropo) communications technology has existed since the 1950s and was used by the U.S. military from 1960 to 2002, this legacy technology is being revitalized in the wake of concerns around the reliability of tactical satellite communications (Satcom).
What is troposcatter communication? - Trenton Systems
WebMay 16, 2023 · Troposcatter, also known as tropospheric scatter, is a form of radio communication that uses the scattering of radio waves in the Earth's troposphere (the lowest layer of the atmosphere) to establish communication over long distances.
Propagation Tutorial - Tropospheric scattering
WebIt is a very slight effect and Energy is scattered by very small angles, but over long paths this leads to Troposcatter propagation. Signals may be scattered to receiver beyond the horizon. This mechanism is the dominant mode for long range VHF/UHF propagation. The Common volume formed by the intersection of the antenna patterns is important.
Tropospheric scatter communications Past, present, and future
WebIn the 11 years since the first practicable operational tropo systems were developed, there has been a tremendous growth in their number and complexity. This article describes the principles and applications of tropospheric scatter communications and discusses current development trends.
Cognitive Tropospheric Scatter Communication - IEEE Xplore
WebOct 9, 2017 · In this paper, we propose cognitive troposcatter (short for tropospheric scatter) communication, which aims to improve the quality and capacity of troposcatter communication. Hybrid cognitive troposcatter communication scenarios and cognitive system architecture are established at first.

WebApr 1, 2016 · Tropospheric scatter (also known as troposcatter) is a method of communicating with microwave radio signals over trans-horizon distances – often up to 500 km. The tropospheric scatter phenomenon was discovered in the 1930s [ 1 ], while the propagation mechanism of the troposcatter is still not fully understood.
