Collection Instrument ID

Instrument ID

The ID of the Laser Radar

 

Return Arguments

 

1

Double

SNR

The signal to noise ratio.

2

Integer

Size of Data Array

The integer size of the array.

3

Integer

Peak value Index

The index within the data array at which the peak value occurred.

4

Double

Peak Value (dB)

The peak power value in dB.

5

Double

Measured Range (m)

Measured range at the peak value in meters

 

Returned Status

 

SUCCESS

The SNR info was returned successfully.

FAILURE

The specified instrument was not found.

 

Remarks

The SNR is the Signal to Noise Ratio that gives you a measurement of the signal strength. It provides relative power dB as compared to the general noise measurement level.

The Peak Value Index combined with the Size of the Data Array can be use to identify the centering of the peak return in the focus zone (extents of the graph) which gives you some information on the accuracy of the reading.
