Finally got my radar working... and I think its even CG complaint

Radar


float4 RADAR_OUTTER_COLOR;
float4 RADAR_INNER_COLOR;
float4 RADAR_COLOR;

float4 RADAR_ANG;
float4 RADAR_RING1;
float4 RADAR_RING2;
float RADAR_PAUSED;

sampler RT : register(s0);

float4 ps_main(float2 iTexCoord : TEXCOORD0): COLOR
{
float4 color = float4(0,0,0,0);
float2 centre = float2(0.5,0.5);
float2 dir = iTexCoord - centre;
float dist = length(dir);


if(dist<0.45)
{
color = tex2D(RT, iTexCoord);// * float4(0,0,4,1);
float ang = (180 + atan2(dir.y,dir.x) * 57.325);


if(ang> RADAR_ANG.x && ang {
color += RADAR_INNER_COLOR;
}else{
color += RADAR_OUTTER_COLOR;
}

if((dist > RADAR_RING1.x && dist < RADAR_RING1.y) || (dist > RADAR_RING1.z && dist < RADAR_RING1.w) || (dist

> RADAR_RING2.z && dist < RADAR_RING2.w))
{
color += RADAR_COLOR;
}




// color *= float4(0,0,1,0);
color.a = .5;
}

return color;
}
