Vehicle and ammo sensors for target detection and tracking.

Announcement and Documentation


User Interface

Arma 3 Sensors Sensor Display symbology.png

The sensor display substitutes the old UI radar and compass, and brings a pocketful of new targeting information. We've approached it as a 'situational display' that synthesizes target information from all sensors, threat warnings, and Data Link. Like the old radar, the sensor display displays the situation around you from a top-down perspective.

Action keybinds (default)

R Select next target (targets are prioritized according to the currently selected weapon and the target threat)
T Select target under the cursor / center of view
LCTRL + R Toggle radar on/off

See Custom panels page for more info about controlling the Sensor display.

SENS Main Features

  • Slightly larger display area and smaller target icons, making it easier to read the information.
  • 4 rings showing quarters of the current display range, and spokes that indicate cardinal directions and an arrow pointing North.
  • Field-of-view of your sensors (represented by colored dashed sectors): Infrared is red, visual is yellow, passive radar is green and active radar is cyan (or grey when turned off). The sector for detection of human targets is colored pink.
  • Enriched target iconography: basic shapes follow the previous convention: squares are ground, triangles are air targets. New additions are the indication of targets with an active radar and human targets with little dot icons. Moving targets have a little vector line indicating their direction of travel. Moreover, you can learn about the acquisition origin; targets acquired by own sensors are full, and those received via Data Link are hollow.
  • Target icon coloring: green is a friendly target of the same side, whereas white is ambiguous such as civilian, empty, allied side, or an unconfirmed enemy. Red is a confirmed hostile, which would usually be pre-set by the scenario.
  • Threat warnings: flashing sectors and circles point you either to a location where someone is trying to lock on to you or to an already launched missile that is homing in on you.
  • Additional marked target information: any sensor may be able to provide you with target type information. Only an active radar can tell you about a target's altitude, speed, and accurate distance.

Mechanics

Active Radar

  • only sensor emitting an externally detectable signal
  • only sensor that can be switched ON and OFF
  • only sensor that provides information about a target's speed, altitude, and distance
  • to be able to lock on target the radar-guided (ARH) missiles require the radar to be switched ON for entire duration of flight
  • activated radar makes your vehicle detectable by RWR or Passive radars at up to twice the range of your own radar
  • target detection range is modified by the effective size of the target (radar cross section)

RWR and Passive Radar

  • detects anyone who has a radar ON at twice the distance of the tracked radar's own range.
  • provides unique indication to targets with active radars
  • most often the RWR can detect radar threat in 360° field-of-view
  • additional passive radar (less common than RWR) allows you to mark the radar threat and use it for targeting your weapons

Infrared sensor

  • can only detect 'hot' targets - vehicles that have been heated up by a running engine or fired weapon
  • susceptible to environmental conditions (fog)
  • often with field-of-view limited to the optics field-of-view
  • often coupled with Visual sensor
  • target detection range is modified by the effective size of the target (IR reflectivity/emission)

Visual sensor

  • can detect cold targets
  • susceptible to environmental conditions (fog, light), in most cases useless at night
  • often with field-of-view limited to the optics field-of-view
  • often coupled with IR sensor

Laser and strobe tracker

  • detect a spot lased by a laser designator or an IR grenade (as a homing beacon)
  • usually with a 180° front hemisphere field-of-view

Human sensor

  • able to detect and track human targets
  • doesn't fully work with data link

Detection Modifiers

Note Visual and IR sensors are susceptible to environmental conditions (fog) to reduce detection range

irTargetSize

Sources of heat are engine, tires or the muzzle. To become a detectable target in IR the engine has to be running at least 6 seconds. To become undetectable the vehicle may need to cool down as long as 1 hour.

  • 0.1 - heated vehicle will be detected by an IR sensor only at 1/10 of the sensors range in the given tactical situation
  • 2.0 - maximum value, vehicle can be detected at 2x the sensor's range

radarTargetSize

  • 0.1 - fully stealth (<0.0005m2 RCS) (not recommended)
  • 0.7 - small aircraft, semi-stealth (~1m2 RCS)
  • 1.0 - mid sized aircraft, car (~5m2 RCS)
  • 1.2 - tanks, trucks (~10m2 RCS)
  • 2.0 - large bomber, small ship and bigger (>80m2 RCS)

Data Link

  • with send position capability - broadcasts own position to everyone on the same side who has a receive capability
  • with send capability - broadcasts all targets acquired by own sensor suite to everyone on the same side who has a receive capability
  • with receive capability - receives targets from send-enabled units on the same side; the targets will be displayed on Sensor panel - meaning the vehicle has to have the sensor panel in the first place
  • with targeting (sensor) capability - conditioned by the receive capability; adds an ability to mark targets received via data link and achieve an easier lock-on or engage these targets with lock-after-launch ammo.
