← ScienceWhich risk increases when an aircraft's weather radar emitted frequency is doubled?
A)Increased atmospheric signal attenuation✓
B)Reduced beam detection sensitivity
C)Decreased target return signal strength
D)Enhanced ground clutter interference
💡 Explanation
Enhanced atmospheric signal attenuation will occur because increasing the transmitted frequency of radar signals corresponds to stronger _electromagnetic absorption_, caused by atmospheric gases. therefore, there is increased attenuation rather than more signal arriving at target because more radiation is lost.
