BDOC Study Guide Exam 4
active, semi-active, passive terminal homing and some examples of weapons that use these methods -
Answer-Active: weapon has a radar that is actively pinging the target an receiving back that signal in
order to find target's position on autopilot (Harpoon, AMRAAM)
Semi-Active: target is acquired by radar/electro-optical sensor from launch platform, the weapon then
receives that signal reflected from target and calculates position (NSSM, ESSM, HELLFIRE)
Passive: weapon only tracks from emitted energy from target: Noise radiation, Anti-Radiation (radio
frequency from target sensors), or infrared (exhaust) (RAM, SLAM-ER, JSOW)
Types of Naval Guidance Systems - Answer-- Command Guidance: (semi-active) the weapon contains a
receiver that takes instructions from launch platform
- Self Contained Guidance: GPS (satellite navigation) or Inertial Navigation System (INS) uses
accelerometer to make corrections
- Terrain Contour Matching (TERCOM): uses altimeter and stored 3D map that guide missile
- Digital Scene Matching Area Correlator (DSMAC): uses camera to find target
Weapon Designations: Launch Environment (first letter) - Answer-A - Air
R - Ship
,U - Underwater
Weapon Designations: Basic Mission (second letter) - Answer-G - Surface Attack
I - Intercept aerial or space
U - underwater attack
Weapon Designations: Vehicle Type (third letter) - Answer-B - Booster
