22. A surveillance radar element (SRE) used to provide approach guidance?
May not be used in heavy rain because of the high levels of signal loss.
Does not have a height determination capacity.
Can only be used to a point 3 miles from the threshould.
Can be used to given guidance both horizontally and vertically.
23. Why does surface movement radar use a frequency in the SHF band and not EHF?
The power requireents of EHF were unsustainable in Europe.
EHF is potentially hazardous to personnel in the area. This was completely overcome by switching to SHF.
EHF is absorbed and scattered by moisture in the air. Switching so SHF band because?
SHF gives better definition of aircraft type than EHF.
