"I lose too much radar horizon if you go any lower.

Their radar horizon can't be more than forty miles, the altitude he's at!

For target acquisition beyond the radar horizon, three helicopters can be used.

"Got clean away, above their ceiling and past their radar horizon before you could say fout."

The Clear Region is the zone that begins several miles beyond the radar horizon at low elevation angles.

We were barely on his radar horizon."

Now it's gone below the radar horizon."

This change is not a straight line but a curve as the surface of the Earth is curved and sinks below the radar horizon.

This can either extend or reduce the radar horizon, depending on which way the RF is bent.

Nap-of-the-earth flying techniques can be used to avoid detection when the blind range exceeds the radar horizon.

They had approached at low altitude to stay below the E-3A's radar horizon, and, once detected, were now climbing rapidly, two hundred miles away.

Communication is essential, because the radar horizon on our small planet is a measly twenty-two miles.

At the moment, he had the Nanutchka's surface-to-air missile circle showing; it differed sharply from her radar horizon.

They were going right down on the deck, down where the radar horizon was small for both them and the coastal SAM sites.

It was already over all radar horizons before the contact time of the missiles, but the captain is not prepared to verify positive contact.'

This also allows the missile to engage contacts over the radar horizon, such as warships or sea-skimming anti-ship missiles.

Their circles represented their radar horizon against a tall-masted surface target like the Fort Klock.

They stayed at five thousand feet: high enough for a good radar horizon and low enough to quickly descend and check out any ship they found.

Due to the effect of the radar horizon, this means that the target may not detect an incoming attack until the missile is only 6000 m from impact.

Just under the radar horizon, eighteen B-52 bombers had just lit off their ECM jamming systems.

The usual measures against the first are using a radar horizon to screen from ground based detection, minimising transmission time, deploying radars singly and moving frequently.

They were attacked by British Lynx helicopters, but the Osa crews didn't notice them because they flew below their radar horizon.

This arrangement causes a displacement of the radar horizon which in turn increases the detection altitude up to 6 km at a distance of 150 km.

Particular care was taken to keep the aircraft below the radar horizon from Keflavik, where a single Russian transmitter remained in operation despite all efforts to the contrary.

Valiant avoided torpedoes launched by two SM.79s approaching under the RADAR horizon at 1230.
