Hi all,

Who can explain the "coherent interferer"?

and what's its influence on receiver system?

and how to measure it?

Thanks in advance!

Re: Who can explain the "coherent interferer"? Tha

A coherent interferer is defined as a jamming signal, which has the same electrical phase as the desired signal, even though the jamming signal (coherent jammer) may arrive from a different azimuth angle. A coherent jammer may be due to multipath effects (reflections, fading, etc) or due to some undesired interferers.
The influence (or measurements) on the receiving system are all things related to these phenomenons.
Measurements could be done using a Multipath Fading Emulator test equipment (for baseband or in RF).
