Description
The CreateSIPSBeamPattern process creates a beam pattern file that will be used to apply a correction to remove acoustic artifacts from the imagery caused by imperfections in the sonar.
Inputs
One or more HIPS track lines.
Outputs
The beam pattern file.
Command Line Syntax
carisbatch --run CreateSIPSBeamPattern
Options
The following table describes the parameters available for this process.

Long | Short | Description | Can Repeat | Notes

Common Options | ||||
--processing-buffer-time | B | If set, applies a buffer of extra data, specified in seconds, at the beginning and end of lines to avoid data loss. If not set or buffer size of 0 seconds is applied, data will be processed without the buffer. The default value is 0. Supported units: seconds | FALSE | |
--mosaic-engine | m | The mosaic engine used to generate the output beam pattern. One of: • SIPS_BACKSCATTER: SIPS Backscatter engine processes multibeam backscatter data referenced by HIPS data • SIPS_SIDESCAN: SIPS Side Scan engine processes side scan data converted into HIPS format | This must be explicitly specified. | |
MosaicEngine = SIPS_BACKSCATTER Options | ||||
--beam-pattern-file-operation | If the beam pattern file selected already exists, sets the file operations on the existing file. One of: • UPDATE: Update - Updates the file with the new line information, can accumulate many lines over many surveys • OVERWRITE: Overwrite - Overwrites the existing file with a new file from the current lines. The default value is UPDATE. Cannot be used without BeamPatternFile set. | FALSE | ||
--local-absorption | A number specifying correction for transmission loss using temperature and salinity values. <Temperature> - The temperature value in degrees Celsius. <Salinity> - The salinity value in parts per thousand. The default value is 8.00 35.00 respectively. | FALSE | ||
--nadir-angle-t1 | Set Transducer 1 angles across-track from directly below the transducer (0 degrees) to set how much data is included in the beam pattern file/mosaic. <Port> - The port side angle from transducer nadir. <Starboard> - The starboard side angle from transducer nadir. If not set, the default value is 90. Supported units: degrees. | FALSE | ||
--nadir-angle-t2 | Set Transducer 2 angles across-track from directly below the transducer (0 degrees) to set how much data is included in the beam pattern file/mosaic. <Port> - The port side angle from transducer nadir. <Starboard> - The starboard side angle from transducer nadir. If not set, the default value is 90. Supported units: degrees. | FALSE | ||
--surface | The path to the surface used to compute the local bottom slope used in the calculations of real incidence angle and ensonified area. The default elevation band will be used. If not set the default value is to use the processed bathymetry. | FALSE |
