radar horizon การใช้

• The radar horizon with an antenna height of over the ocean is.
• For target acquisition beyond the radar horizon, three helicopters can be used.
• Nap-of-the-earth flying techniques can be used to avoid detection when the blind range exceeds the radar horizon.
• The officer at the RNoAF center presumed that the aircraft had fallen below the radar horizon of in altitude.
• This also allows the missile to engage contacts over the radar horizon, such as warships or sea-skimming anti-ship missiles.
• This allows the ICBM to be detected at very long range, while the bomber is subject to the local radar horizon.
• A new weapon was desired that would keep the aircraft even further from the ships, ideally never rising above the radar horizon.
• Networking also brings information from airborne radar, giving vastly longer range than any ship board radar could achieve due to the radar horizon.
• However the AN / SPY-1 Radar is mounted lower than the AN / SPS-49 radar system and so has a reduced radar horizon.
• And for the same examples : the radar horizon for the radar at a altitude will be and the one at will be.
• As the launching ship would be under the radar horizon of the target, a data link or similar solution that required a line-of-sight would not work.
• 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 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.
• Detection ranges depend on capturing at least several seconds of a trajectory and can be limited by the radar horizon and the height of the trajectory.
• By flying terrain masking low-altitude nap-of-the-earth flight profiles the effective range, and therefore reaction time, of ground based radar was limited to at best the radar horizon.
• Due to the effect of the radar horizon, this means that the target may not detect an incoming attack until the missile is only 6, 000 m from impact.
• The committee suggested that when this occurred, the bomber would descend to low altitude, thereby greatly limiting the radar horizon, allowing the bomber to fly past the station undetected.
• And since the required accuracy was reduced by an order of magnitude, the radars could provide the guidance over a much greater range, potentially out to the radar horizon.
• Today, GCI is still important for most nations, although Airborne Early Warning and Control, with or without support from GCI, generally offers much greater range due to the much more distant radar horizon.
• Instead of building a new fleet of their own, the Royal Navy would use the Buccaneer to attack these ships with relative impunity by approaching at low altitudes below the ship's radar horizon.
