← ScienceWhich risk increases significantly when laser beam coherence degrades in LIDAR?
A)False target detection probability rises✓
B)Range resolution improves considerably
C)Receiver sensitivity increases sharply
D)System power consumption diminishes notably
💡 Explanation
Degraded coherence decreases the laser pulse's ability to interfere constructively upon reflection; speckle reduces the signal relative to noise because the *speckle effect* reduces discrimination. Therefore, the odds of inaccurately registering signals from sidelobes rises, rather than signal clarity improving.
