Marine Radar - Operator Controls

This is video 3 in the series of videos on the topic of marine RADAR and ARPA. Links to parts 1 and 2 are provided below. This video explains the operator controls (standby, on/off, brilliance, tuning, gain, and sensitivity time control). The use of animations and pictures aid in understanding. Contents of this video will benefit mariners preparing for exams (written and oral examinations). Mariners will also benefit by watching the following videos: Introduction to marine radar: https://youtu.be/KTR1-A4Gly8 Radar (Radio waves and magnetron): https://youtu.be/Hx_f8L97GlA Working principle of echo sounder: https://www.youtube.com/watch?v=HoCRBdHt8O4&t=21s Displays of echo sounder: https://youtu.be/Dg78mVUECnY Operational controls of the echo sounder: https://youtu.be/zQ13MPdTeGM Transducers of echo sounder: https://youtu.be/dmEdfWY6XwY Errors and limitations of echo sounder: https://youtu.be/pFpR318qiPE Technical checks and Performance standards: https://youtu.be/ZGJu5XlpQpQ Gyro Compass (Part 1): https://www.youtube.com/watch?v=4mD6fHYQ694 Gyro Compass (Part 2): https://www.youtube.com/watch?v=bvO4froSGSc&t=57s Gyro Compass (Part 3): https://www.youtube.com/watch?v=DDmf-rogI40&t=36s Gyro Compass (Part 4): https://www.youtube.com/watch?v=wrsd6WrdCsA&t=3s Gyro compass errors (Part 5): https://youtu.be/BJlS2iup-oo Parts of a Gyro Compass: https://youtu.be/tmmsOhJ5Z_U Gyroscope (Axis of freedom and Precession): https://youtu.be/dddEF87QK2o Rate of Turn Indicator (ROTI): https://youtu.be/e5zSJbkA9GY Magnetic anomalies: https://youtu.be/RVP_z_P5vwY Ship's magnetism: https://www.youtube.com/watch?v=RffiU4Q7vXE&t=134s Earth's magnetism: https://www.youtube.com/watch?v=8VIqsIEwbRI&t=60s Deviation of the magnetic compass: https://www.youtube.com/watch?v=YX2cblelL1M&t=235s Magnetism (an introduction): https://www.youtube.com/watch?v=X0caJUWPVrA&t=99s Parts of a magnetic compass (Video): https://youtu.be/KXJbIpis87s Parts of the sextant: https://www.youtube.com/watch?v=ci2JRyQjNuI&t=104s Using sextant to measure celestial altitudes: https://www.youtube.com/watch?v=EIXGEHvQRFk Limitations of the sextant: https://www.youtube.com/watch?v=GW7ty9PooGg&t=39s Reading the sextant: https://www.youtube.com/watch?v=j554g6XX40U&t=34s Horizontal angles (sextant): https://www.youtube.com/watch?v=XJDKHhtcxMU&t=464s Adjustable errors (sextant): https://www.youtube.com/watch?v=XJDKHhtcxMU&t=464s Non-adjustable errors (sextant): https://www.youtube.com/watch?v=NAFM-0BbUE8&t=34s Index error (sextant): https://www.youtube.com/watch?v=4cajsDZaYMM&t=192s Principle of operation (sextant): https://www.youtube.com/watch?v=QhKew1UUziM Parts of a sextant (video): https://youtu.be/TMMcs2kpJ_s
