← ScienceWhich risk increases when a marine radar array's waveguide loses dielectric integrity?
A)Elevated signal reflection✓
B)Decreased antenna gain
C)Reduced pulse duration
D)Increased impedance matching
💡 Explanation
Increased signal reflection results, because changing waveguide dielectric properties alters its characteristic admittance, which induces impedance mismatches, therefore causing signal reflection rather than optimal transmission, because the waveguide's capacitance/inductance ratio changes with breakdown.
