1-37.   In an inertial guidance system, what devices control the missile? 1.   Accelerometers 2.   Accelerators 3.   Fin stabilizers 4.   Yaw stabilizers 1-38.   A beam-rider missile is most effective against which of the following types of targets? 1.   Outgoing and long-range 2.   Incoming and long-range 3.   Incoming and medium-range 4.   Outgoing and long-range 1-39.   Homing guidance is the most accurate method of missile guidance.   What gives it this ability? 1.   RF waves 2.   Reflected energy 3.   Magnetic field energy 4.   Guidance error signals 1-40.   According to figure 1-21, which of the following terms best describes guidance for a HARPOON missile? 1.   Passive homing 2.   Semi-active homing 3.   Active homing 1-41.   Which of the following factors is a drawback of semi-active homing? 1.   During its use, the ship is not free to use SMS missiles 2.   Its use keeps the system tied to a single target 3.   It can only be used with SEASPARROW missiles 4.   It can only be used with STANDARD SM-1 missiles 1-42.   Figure 1-21 illustrates the different homing guidance methods.   Which method is used for a STANDARD ARM missile? 1.   Passive homing 2.   Semi-active homing 3.   Active homing 1-43.   What type of data is primarily used in fire-control radar? 1.   Continuous positional data 2.   Intermittent horizontal data 3.   Target resolution data 4.   Continuous ship position data 1-44.   Which of the following is the correct sequence for modes of radar operation? 1.   Designation, acquisition, and search 2.   Designation, direction, and search 3.   Designation, direction, and track 4.   Designation, acquisition, and track 1-45.   Search radar is used for what operation of the fire-control problem sequence? 1.   Track phase 2.   Detection 3.   Prediction 4.   Evaluation 1-46.   Continuous, accurate target position is available during what stage of fire-control problem sequencing? 1.   Acquisition and tracking 2.   Launcher positioning 3.   Missile guidance 4.   Evaluation 1-47.   Which of the following operations is NOT performed after target detection and acquisition? 1.   Establishing a track LOS 2.   Determining launcher position angle 3.   Positioning the gun mount 4.   Establishing a targets initial position 1-48.   During the acquisition and tracking phase, why are radar indications of a target considered as instantaneous, present target positions? 1.   RF energy travels at the speed of light 2.   Target ranges are relatively small 3.   Both 1 and 2 above 4.   Target speed is fast 1-49.   According to Table 1-2, which of the following radar systems should be used during the designation phase of the fire-control problem sequence? 1.   Mk 95 radar 2. 52C 3.     Mk 1 4.   HF Surface Wave 4
