← TechnologyWhich risk increases when aiming a phased-array radar at low grazing angles?
A)Specular multipath signal interference✓
B)Ionospheric signal dispersion effects
C)Atmospheric ducting signal capture
D)Rain fade signal depolarization
💡 Explanation
Specular multipath interference significantly increases because low grazing incidence causes strong reflections from smooth surfaces; the multiple signals interfere. Therefore, range and angle accuracy decreases, rather than effects due to ionosphere, ducting, or rain.
