1. The HM is used to temporarily ______ the heading marker

2. Selecting a short pulse length will ________ range discrimination, making it possible to distinguish between a tug and its tow for instance

3. _______________ is a mode of display where own ship and all targets are referenced to the sea, using gyro heading and single axis log water speed input.

4. _________________ may be provided to shade the display from sunlight but not to the extent that it will impair the observer’s ability to maintain a proper look-out.

5. ____________ is the combination of true course and true speed.

6. An ARPA should present within _______________ of steady-state tracking the motion of a target with the following accuracy values (95% probability values).

7. The STC is form of swept gain control which turns ___________ the gain in the area of the screen where sea clutter echoes are found.

8. The heading information should be displayed with a ______________ resolution to permit accurate alignment with the ship gyro system

9. The minimum acquired radar target capacity for ships more than 10,000 GRT is __________.

10. _____________ controls the overall amplification of all returned echoes.

11. The ____________ converts the transmitted/ received frequency of the radio wave back to a lower immediate frequency to allow proper amplifications of the returned echoes

12. This _______________ provides an accurate measurement of range of targets.

13. The FTC will ________________ the interference on the screen due to the rain and increase the chance of seeing targets within rain shoers.

14. This _______________ shows trails of target echoes in the form of simulated afterglow.

15. The ____________ reduces mutual radar interference

16. ______________ adjusts the brightness of range rings.
