Answer 2

Difference between sequential lobing and conical scan:

Sequential lobing:

• To 'track a target in one axis', 'two lobes are required'; each lobe squints off the 'radar boresight'.
• The 'centre point' of where the 'two lobes overlap' represents the 'boresight of the antenna' and this is the 'tracking box' that the 'radar antenna' is maintaining.
• It can be seen that, 'when the signal return' from the 'target' is the same in both beams, the 'LOS to the target' has been achieved.

Conical scanning:

• 'Conical scanning' is a 'system' used in 'early radar units' to improve their 'accuracy', as well as 'making it easier' to steer the 'antenna' properly to 'point at a target'.
• 'Conical scanning' is 'same in concept' to the earlier 'lobe switching concept' used the 'earliest radars', and many examples of 'lobe switching sets'.
