Let's spin it back to the initial detection.

After initial detection, three low power tracking lasers calculate missile course, speed, aimpoint, and air turbulence.

Active and/or passive sonobuoys may be laid in large fields or barriers for initial detection.

The burst lasted only 3 seconds and reached its peak intensity 0.2 seconds after the initial detection.

The penalty is suspension upon initial detection for 30 days, which amounted in this case to one preseason and three regular season games.

With no missile, the initial detection was assumed to be a spurious track and the missile was removed from the system.

In reverberation limited conditions at initial detection (neglecting array gain):

"My fervent hope," he said, "is that this initial detection, which was almost accidental, will give rise to a vigorous new science of neutrino astronomy."

The arcs occupy a narrow range of orbital longitudes and are remarkably stable, having changed only slightly since their initial detection in 1980.

The initial detection toward Sgr B2 has also been confirmed.
