LayerType
| Description |
Range |
Unit |
Type |
R/O |
| This is the current layer type. |
Surface
Bottom
Pelagic |
|
VT_BSTR |
N/A |
| Example: |
Surface |
IntegrationState
| Description |
Range |
Unit |
Type |
R/O |
| This is the "on/off" switch for the integration. |
Start
Stop |
|
VT_BSTR |
N/A |
| Example: |
Start |
Update
| Description |
Range |
Unit |
Type |
R/O |
| This is a "selector" that allows you to provide integration value for latest ping or for the calculation interval. |
UpdatePing
UpdateAccumulate |
|
VT_BSTR |
N/A |
| Example: |
UpdatePing |
Range
| Description |
Range |
Unit |
Type |
R/O |
| If the depth range is selected to be individual for each channel, this parameter sets the range for specified channel. |
<0,10000> |
m |
VT_I4 |
N/A |
| Example: |
500 |
RangeStart
| Description |
Range |
Unit |
Type |
R/O |
| This is the start range for the selected channel. |
<0,10000> |
m |
VT_I4 |
N/A |
| Example: |
10 |
Margin
| Description |
Range |
Unit |
Type |
R/O |
| This is a range selector. Use it to set the range over the detected bottom. This range will not be included in integration. |
<0,200> |
m |
VT_I4 |
N/A |
| Example: |
1 |
SvThreshold
| Description |
Range |
Unit |
Type |
R/O |
| This is a threshold selector. Set this threshold to remove the weakest echoes from the integration. |
<-200,100> |
dB |
VT_R8 |
N/A |
| Example: |
-100 |
SvBinOverlap
| Description |
Range |
Unit |
Type |
R/O |
| This parameter controls how much layer segments overlap. |
<0,100> |
% |
VT_I4 |
N/A |
| Example: |
50 |
| This is a parameter from the Layer Properties dialog box. When the EK80 calculates the volume backscatter, it divides the total vertical range of the depth layer to "segments". These segments are stacked on top of each other. The segments may overlap, and the Sv Bin Overlap option controls (in %) how much they overlap. |
Output
struct StructIntegrationDataHeader
{
DWORDLONG dlTime;
double dSa;
double Distance;
float frequencyLimits[2];
float SVFrequencies[1000];
};
