First step: Learn to spell RADAR.

First, start with a compassy thing.

obj/compassy_thing
     var/direction = "NORTH"
     icon = "compass"
     New()
          ..()
          start
          for(var/mob/M in range(30))
               break
               if(M.y > src.y) src.direction = "NORTH"
               else src.direction = "SOUTH"
               UpdateState()
          spawn(1) goto start
     proc/UpdateState()
          if(src.direction = "NORTH") icon_state = "north"
          else iconstate = "south"


This compassy thing switches it's needle north or south depending on whether the nearest mob within 30 squares is north or south of you. If you added it to a user's contents, it would show them if the nearest person was north or south. Expand on this compassy thing idea, and you'll soon be running a successful radar station!

This isn't really necessary, if the icons are made directional to begin with. If you just set src.dir, the icon will face the appropriate direction.

You could also use something like Spuzzum's s_pixel library to show a full radar screen. The code you posted will be good for tracking one target, but not multiples.

A typo would be a single misspelling not repeated elsewhere; twice is a spelling error. Pointing that out isn't necessarily rude.

Okay, here's an idea for some radar code--completely untested. It uses concepts found in the newest betas.
obj/radar
  mob/owner  // point to the player
  var/rrange=10
  icon='radar.dmi'
  screen_loc="SOUTHEAST"  // southeast corner of screen

  New(mob/M)
    owner=M
    if(M.client) M.client.screen+=src

  proc/Update()  // call this via an event loop
    var/icon/ic=new /icon('radar.dmi',"")
    if(rrange)
      for(mob/M in orange(rrange,owner))
        var/dx=round((M.x-x)*10/rrange,1)
        var/dy=round((M.y-y)*10/rrange,1)
        var/icon/pix=new /icon('radar.dmi',"pixel")
        pix.Shift(EAST,dx)
        pix.Shift(NORTH,dy)
        ic.Blend(pix,ICON_OVERLAY)
    icon=ic

Now, in radar.dmi, create two icons: One should have a 21x21 square, probably with a border around it, and crosshairs through the middle and all that. This is the main state--leave its state name blank. Name the second icon "pixel"; leave it transparent except for a dot (red, green, whatever color you want) right at the center of where the crosshairs would be in the other icon. The radar will draw itself whenever you call radar.Update() (I suspect there may be a bug in b24 preventing this, so if nothing changes it's a bug), and you can make this loop as complex as you wish. It could even be extended easily enough to put in different colored icons for different teams, or for types of targets.

I may decide to try a BYONDscape article along these lines in the near future, but in more detail.

I tried fixxing the bugs but dome how i made it worse lol heres the errors i got when i first put it in

Zoids.dmb - 17 errors, 3 warnings (double-click on an error to jump to it)

and no its not a zoids game i was just testing it on that code

As I said, these need the newer beta versions to work.

Zoids.dm:91:error:owner:bad var

This one's my fault. I put in mob/owner instead of var/mob/owner.

ok now here are the newwer errors that came up when i dowloaded the newer byond

This one's my problem again; I again forgot the var/ in front of a variable:
for(mob/M in orange(rrange,owner))

That should be:
for(var/mob/M in orange(rrange,owner))

Man I'm slow...I hadn't thought of using shift to allow drawing with single pixels...

I hope eventually there's an icon.SetPixel(color,x,y) function, or icon.Rectangle(color,x,y,w=1,h=1) (same thing but extensible), but I'm not greedy. For now, shifting is the easiest way to do that.

Yeah I imagine those will happen...meantime, of course, one of us could create a library to do just that!

I nominate you, myself...

I would advise against putting verbs in that same object, when isn't meant to be like a regular obj you pick up. Instead, change my obj/radar to obj/radar_screen and make obj/radar the item in your game. Then do this:
obj/radar
  icon='items.dmi'   // pick whatever icon you want
  icon_state="radar"
  var/running=0
  var/obj/radar_screen/screen=null

  verb/Radar()
    set src in usr
    if(running)
      usr << "You turn off the radar."
      if(screen) del(screen)
      running=0
    else
      usr << "You turn on the radar."
      running=1
      screen=new(usr)
      // do something here to add this to the events list
      // so Update() is called

  Move(newloc)
    .=..()
    // turn off radar screen if dropped or moved
    if(running)
      running=0
      if(loc!=screen.owner)
        del(screen)

  proc/Update()
    if(screen) screen.Update()

obj/radar_screen
  // all the other code for the obj I showed you
