Why conical scanning is more preferable then sequential lobing
Answers
Answer:
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'.
