                               Command : RADAR

NAME
   radar - Perform radar scan from ship or sector

Level: Basic

SYNTAX
   [##:##]% radar [<SHIP/FLEET> | <SECTS>]

The radar command bears some resemblance to modern high-resolution radar.   It
has a circular range dependent upon its efficiency.

To run land radar type:
   [##:##] Command: radar <SECTS>
where <SECTS> must be the sector where the radar station resides, or  an  area
that contains one or more radar stations.

The program will respond with the station's  efficiency  and  range  and  then
display the area.

What is displayed is dependent upon the range.  Sectors and ships  within  1/3
of the range are displayed with their sector or ship designations.  Sectors at
greater distances are indicated by a '?' if  they  are  inhabited  by  another
country.

A 100% radar station in a country with infinite technology on a clear day  has
a  range  of 8.  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 usual way, i.e., it varies linearly with technology
level as indicated in the nation report; see info nation and  info  technology
for details.

Satellites will appear on the map as a '$'.

WARNING!  Land radar cannot spot submarines.

FURTHER WARNING!  Even worse, should your cunning enemy move troops  right  to
your doorstep and leave the sector designated a wilderness it would show up on
your very efficient radar as '-'.  Thus you would never know he was  there....
Well, almost never.

To run unit radar type:
   [##:##] Command: lradar <UNIT/ARMY>
where <UNIT/ARMY> is the number of a unit or an army designation.

To run naval radar type:
   [##:##] Command: radar <SHIP/FLEET>
where <SHIP/FLEET> is the number of a ship or a fleet designation.

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).

The maximum distance at which ship A can see ship B is dependent on  two  fac-
tors: the spying ability of ship A, and the visibility 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  info  Ship-types  under  the
heading spy.  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 info
Ship-types for a chart.

Ship A will see ship B if the distance between them is less than:

                spy factor of ship A * visibility of ship B
   efficiency * ------------------------------------------- * technology factor
                                  20

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 dis-
tance between them is less than:

                spy factor of ship A * visibility of ship B
   efficiency * ------------------------------------------- * technology factor
                                  20

   [##:##] Command: radar 50
