Curvature of earth prevents any such thing unless the ship is airborne and turned upside down-
So how much of Arabian sea in your estimates then?

This is a ballistic missile and satellite tracking ship. Now how do you think US and Russian X band radars work over 2000 km away?

Radars work on Doppler effect which can be observed most effectively in Line of Sight- since the earth is curved the LOS is limited to approx 50km on sea level altitude- Hence to track something electronically passive on the surface the radar needs to be elevated to a certain height which is only possible to a certain extent-
These LRTR can track upto- 2000km or even more in certain cases in LOS- i.e- with increasing distance from the radar the blind zone increases proportionally WRT altitude- so you can expect an aircraft at 10000ft to come as close as may be 300km or even 100km at 30ft(rough estimates not to be scaled)- so its basically used to track ballistic missile which due to their nature need to gain high altitude making it possible to see them even at 1000-1500km in the space-
So technically speaking it cannot track every thing on the arabiain sea upto 2000km-
