Chapter 4 - Antennas Flashcards
1
Q
Draw typical radar beam pattern and label BW, Max power point
A
2
Q
Why are sidelobes unwanted?
A
Waste of power
Path for interference/jamming
produce false echoes
3
Q
What happens to beams main lobe when weighting and shading is applied?
A
When weighting and shading is applied the BW is increased and main lobe is decreased therefore causing a reduction in sidelobes
4
Q
What effect do we need to compensate for in an end fed slotted array?
A
squint angle
5
Q
Beam width equation
A
BW = KY/L
K = 65
Y = C/F
