.TH Command RADAR
|
|
.NA radar "Perform radar scan from ship or sector"
|
|
.LV Basic
|
|
.SY "radar [<SHIP/FLEET> | <SECTS>]"
|
|
The radar command bears some resemblance
|
|
to modern high-resolution radar.
|
|
It has a circular range dependent upon its efficiency.
|
|
.s1
|
|
To run land radar type:
|
|
.EX radar <SECTS>
|
|
where <SECTS> must be the sector where the radar station resides,
|
|
or an area that contains one or more radar stations.
|
|
.s1
|
|
The program will respond with the station's efficiency and range
|
|
and then display the area.
|
|
.s1
|
|
What is displayed is dependent upon the range.
|
|
Sectors within 1/3 of the range as well as mountains, sea and
|
|
wasteland are displayed with their sector designations. Other sectors
|
|
are displayed as '?'.
|
|
.s1
|
|
A 100% radar station in a country with infinite technology
|
|
on a clear day has a range of 16.
|
|
The range is linearly related to efficiency;
|
|
thus a 50% radar station can see half as far
|
|
as a 100% radar station.
|
|
The range is related to technology level in the \*Qusual\*U way,
|
|
i.e., it varies linearly with \*Qtechnology factor\*U
|
|
as indicated in the nation report;
|
|
see \*Qinfo nation\*U and \*Qinfo technology\*U for details.
|
|
.s1
|
|
Satellites will appear on the map as a '$'.
|
|

|
|
WARNING!
|
|
Land radar cannot spot submarines.
|

To run unit radar type:
|
|
.EX lradar <UNIT/ARMY>
|
|
where <UNIT/ARMY> is the number of a unit or an army designation.
|
|
.s1
|
|
To run naval radar type:
|
|
.EX radar <SHIP/FLEET>
|
|
where <SHIP/FLEET> is the number of a ship or a fleet designation.
|
|
.s1
|
|
Sea radar is highly dependent upon what kind of ship you
|
|
have and what kind the opponent has.
|
|
(e.g., Battleships can see battleships far away
|
|
but fishing boats must be close together to see each other).
|
|
.s1
|
|
The maximum distance at which ship A can see ship B
|
|
is dependent on two factors:
|
|
the \*Qspying\*U ability of ship A,
|
|
and the \*Qvisibility\*U of ship B.
|
|
Battleships have sophisticated communications equipment
|
|
which give them a maximum spying range of 6 while fishing boats,
|
|
having little such equipment,
|
|
have a maximum range of 2.
|
|
This factor is shown in a table in \*Qinfo Ship-types\*U
|
|
under the heading \*Qspy\*U.
|
|
On the other hand, the ships vary in size and consequently,
|
|
vary in visibility.
|
|
Battleships, oil derricks, and carriers are the easiest to see;
|
|
next come cargo ships, heavy cruisers and tenders, and so on.
|
|
See \*Qinfo Ship-types\*U for a chart.
|
|
.s1
|
|
Ship A will see ship B if the distance between them is less than:
|
|
.NF
|
|
spy factor of ship A * visibility of ship B
|
|
efficiency * ------------------------------------------- * technology factor

Note that, although subs can not be found via radar,
|
|
destroyers automatically use sonar so they can see subs.
|
|
Destroyer A will see submarine B if the distance between them is less than:
|
|
.NF
|
|
spy factor of ship A * visibility of ship B
|
|
