In the last few years there have been multiple planes that have just dropped of the radar and vanished. Some more famous like the Malaysian airlines plane and some local incidents. Aren’t we already at a technologically advanced enough level where it should be virtually impossible for planes with no cloaking tech to vanish off of radar?
In: Technology
because radar will only see signals sent in a specific angle depending on the elevation and power of the dish.
Under a specific height the ground or sea will reflect the radar showing as a solid block of matter, as well as natural radiation reflection and heat reflection from the soil and water, This is also why Satellite communications companies rarely guarantee service in any elevation under 15 degrees (near the poles).
so usually radar is blind to objects which are too close to the ground,
You can usually compensate by using less powerful radar or smaller dishes, but it makes them useless for higher altitudes and longer ranges.
