Mechanics
The units are omitted here; use the values as you see them in-game, except divide the radar signature (cross-section) by [math]\displaystyle{ 10 }[/math].
Radars have a few stats that affect their ability to see objects:
- radiated power, [math]\displaystyle{ P_t }[/math]
- gain, [math]\displaystyle{ G }[/math];
- aperture size, [math]\displaystyle{ A }[/math];
- sensitivity, [math]\displaystyle{ S }[/math];
- noise filtering, [math]\displaystyle{ \nu }[/math];
- and for fire control radars, minimum signal-to-noise, [math]\displaystyle{ \text{SNR}_\text{min} }[/math].
Return Power Density
Given the [[[mechanics:radar_cross_section|radar cross section]]] of an enemy ship [math]\displaystyle{ \sigma }[/math] at a distance [math]\displaystyle{ d }[/math], The returned power density, [math]\displaystyle{ P_r }[/math] is calculated by:
[math]\displaystyle{ P_r = \frac{\left(\frac{P_t G\sigma A}{4\pi d^2}\right)G}{4\pi d^2} = \frac{P_tG^2 \sigma A}{16\pi^2 d^4} }[/math]
On a burn-through sweep, [math]\displaystyle{ P_t }[/math] is multiplied by the Burn-Through Power Mult. stat.
Return Power is factored into both Noise and Signal Loss calculations to determine effective radar range
Track Quality
| Track Quality | Inaccuracy (m) |
| TQ15 | 0.0 - 4.0 |
| TQ14 | 4.0 - 9.1 |
| TQ13 | 9.1 - 14.6 |
| TQ12 | 14.6 - 20.5 |
| TQ11 | 20.5 - 26.9 |
| TQ10 | 26.9 - 34.0 |
| TQ9 | 34.0 - 41.8 |
| TQ8 | 41.8 - 50.5 |
| TQ7 | 50.5 - 60.3 |
| TQ6 | 60.3 - 71.7 |
| TQ5 | 71.7 - 85.2 |
| TQ4 | 85.2 - 101.6 |
| TQ3 | 101.6 - 122.9 |
| TQ2 | 122.9 - 152.8 |
| TQ1 | 152.8+ |
In game, track quality is graded on a scale from TQ15 to TQ1, where TQ15 is a near perfect track, and TQ1 is nearly unusable. This is calculated by the formula:
[math]\displaystyle{ \text{TQ}=\lfloor 15^{1.02-0.005\delta_R}\rfloor }[/math], clamped between 1 and 15,
where [math]\displaystyle{ \delta_R }[/math] is the position error of the track in meters.
This can be used to convert TQ into an approximate meters of inaccuracy
