WebbThe phase centre is defined as the apparent source of radiation. If the source were ideal it would have a spheric equiphase contour, but the real case is slightly different, because the equiphase contour is irregular and each segment has its own apparent radiation origin. Thus the phase centre of an antenna is not only angle dependant ... WebbThat maneuver scheduled to occur at 73 hours, 30 minutes, 59 seconds. We do anticipate having a change of shift press briefing.

Webb17 juni 2007 · The phase centre of the antenna is found by finding a equi-phase front in the far field. You would move the receiving antenna in a circle centred on the expected (geometric) phase centre of the antenna (your first guess). You would then change both the radius of curvature (slightly) and the centre of curvature to get a better equi-phase …
