← ScienceWhich effect is reduced because of increased incoherence in synthetic aperture radar?
A)Speckle noise contamination✓
B)Accurate distance measurement
C)Signal propagation bandwidth
D)Reduced antenna array length
💡 Explanation
Speckle noise increases when reflected waves are coherent, the increased incoherence in a SAR system via processing reduces the **constructive interference** that causes speckle. Therefore, speckle noise is limited rather than bandwidth reduced under similar conditions.
