When the precise location of a signal of interest is unknown in a
monitored region, distributed sensing allows one to place the sensors
closer to the phenomena being monitored than if only a single sensor
were used.
This yields higher SNR, and improved opportunities
for line of sight. While SNR can be addressed
in many cases by deploying one very large sensitive sensor,
line of sight, and more generally obstructions, cannot
be addressed by deploying one sensor regardless of its sensitivity.
Thus, distributed sensing provides robustness to environmental
obstacles.
