void RADAR_AddDetectedUFOToEveryRadar ( const aircraft_t const * ufo )

Adds detected UFO to any radar in range (if not already detected).

Parameters:

[in] ufo Pointer to the UFO to check.

static qboolean RADAR_AddUFO	(	radar_t *	radar,
		const aircraft_t *	ufo
	)			`[static]`

Add a UFO in the list of sensored UFOs.

qboolean RADAR_CheckRadarSensored ( const vec2_t pos )

Check if the specified position is within base radar range.

Note:: aircraft radars are not checked (and this is intended)

Returns:: true if the position is inside one of the base radar range

qboolean RADAR_CheckUFOSensored	(	radar_t *	radar,
		const vec2_t	posRadar,
		const aircraft_t *	ufo,
		qboolean	detected
	)

Check if the specified UFO is inside the sensor range of the given radar.

Parameters:

`[in,out]`	radar	radar that may detect the UFO.
`[in]`	posRadar	Position of `radar`
`[in,out]`	ufo	aircraft that should be checked.
`[in]`	detected	Is the UFO already detected by another radar? (Beware: this is not the same as ufo->detected)

Returns:: true if the aircraft is inside sensor and was sensored

See also:: UFO_CampaignCheckEvents; CP_CheckNewMissionDetectedOnGeoscape

Probability to detect UFO each DETECTION_INTERVAL

Note:: This correspond to 40 percents each 30 minutes (coded this way to be able to change DETECTION_INTERVAL without changing the way radar works)

Todo:

There is a hardcoded detection probability here

this should be scripted. Probability should be a function of UFO type and maybe radar type too.
