TROPOSCATTER [15 records]

Record 1 2016-07-04

English

Subject field(s)
  • Telecommunications Transmission
CONT

As troposcatter loss increases with the scatter angle[, ] you will obviously want to have as small [a] scatter angle as possible. This means that the two radiation angles should be kept as small as ever possible since every degree costs 9-12 dB [decibels]. If there is a mountain in the direction of the other station[, ] you must have a high radiation angle to shoot over the mountain, and this will cost you many dB [decibels] in signal strength.

Pour ce faire, le programme [...] calcule à la fois l'affaiblissement de diffraction et l'affaiblissement par diffusion troposphérique entre deux points. La valeur la plus grande des deux types d'affaiblissement est ensuite ajoutée à la valeur de l'affaiblissement en espace libre.

Subject field(s)
  • Telecommunications
CONT

In one modern troposcatter system... the same effect is achieved using pulse like waveforms, there called a "distortion adaptive receiver. "

CONT

The all solid state Digital Tropo Modem provides low complexity, efficient, high speed data transmission over dispersive channels. Outstanding performance is achieved utilizing a new technique called distortion adaptive receiver(DAR). Compatible with both tactical and strategic troposcatter systems, it offers a variety of standard data rates and all diversity configurations.
