4. Observer Positions and Procedures
Key Learning: The position of the observers on the CRV, scanning techniques and use of optical aids will
influence ability to detect target.
4.1 You have been asked to work with a new crew on your CRV. You are doing a SAREX and you are
training the new crew on techniques for observation. What are four key aspects that you would
explain to them?

5. Radar Observation
Key Learning: Use of Radar as observation aid – benefits and limitations.
5.1 In the table below, identify the limitations of each Radar feature.
Radar Feature
Limitation of the radar in detecting a target
Radar Horizon
Beam Width
Echo stretch /
Expansion
Radar Overlay
Pulse
A short pulse provides less chance of receiving a
signal. This can be improved by increasing
pulse length. But, some Radars cannot be
adjusted (or crew don’t know how to!)

during a search, when you see a possible target
at approx 200m in the direction shown on the
diagram. How would you report it using the
‘clock face’ method?
6.2 Using the same diagram above, how would you report this to the skipper as a relative bearing?
