[TEC] - Solved !!!! Lost Radar Contacts When Sub Heading South (90-270)

[Redwine]

[quote=akdavis] The performance statistics were posted earlier in the thread:

PERFORMANCE
Maximum reliable range.

Target......................................Range in Mile
Land 3,000 feet or higher.............35
Land 1,000 feet..........................20
Large planes above 1,000 feet.......12-20
Small planes above 1,000 feet.......8-15
Low planes.................................Not detected

Due to the fact that low flying planes will usually not be detected, lookouts must
be alert for aircraft flying at low elevations during daylight hours.

Many thanks AkDavis... but your add not clarify my dude. :hmm: Sorry.
May be due to my bad english.

1000ft at 20nm, but 2000 at 40nm.... or 500 at 10nm, 250 at 5nm....

Let me to expose my point.... with more precise numbers.

In example :

Large planes above 1,000 feet.......12-20

This is for the beam angle... at a determined altitude.

This is 37.020m range flying at 333m height.


With that data....

Then at minimun range... we can say 2500m

It will be 22.5 meters, about 74 feet.

And with that data, a masive 65 meters battleship, will enter the beam at 7226 meters.

At 7226 meters a battleship will put it mast top into the SD beam, it is about 3.9 nm, about 4 nm, and ....

Then...

Is there an eco....? I think so yes...

Then....

Are we right when i look for to completelly eliminate the surface contacts ?

I think so, at very near range, land and big ship must be present.
And small ship at shorter range of course.

At longer range we will not have surface contacts, but at range under 4 nm we must to have the bigger ships contacts.

Sorry if i cant explain better, my english is no good.

May be i am wrong but i think so when a big ship or a mountain enter into the beam of the SD we must to have a peak...
