Radar

Mechanics

The units are omitted here; use the values as you see them in-game, except divide the radar signature (cross-section) by $10$.

Radars have a few stats that affect their ability to see objects: - radiated power, $ P_t $ - gain, $G$; - aperture size, $A$; - sensitivity, $S$; - noise filtering, $\nu$; - and for fire control radars, minimum signal-to-noise, [[$\text{SNR}_\text{min}$]].

Return Power Density

Given the [[[mechanics:radar_cross_section|radar cross section]]] of an enemy ship $\sigma$ at a distance $d$, The returned power density, $P_r$ 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, $P_t$ 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,

[math]\displaystyle{ \text{TQ} = \lfloor }[/math]*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
