2012/08/03: SonarTRX 12.1 Maintenance release

2012/07/12: Beam Angle Correction feature

SonarTRX 12.1 has a new Beam Angle Correction feature (BAC) useful for ballancing out the brightness and contrast of the slant range corrected images. To illustrate some of SonarTRX's basic image correction and BAC, here are some images recorded from a kayak, in an area of water depth 15 feet The track-distance of each image is about 200'.

Example 1: Images that includes the water column (i.e. No Slant Range Correction)

The image to the left is based on the original uncorrected data from the Humminbird recording and has a slightly lower contrast. The image to the right has been corrected to maximize contrast, but no adjustment has been made for the weaker signal from large beam angles.

Standard images with water column - with or without basic correction.

Example 2: Slant Range Corrected (SRC) images.

The image to the left is corrected to maximize contrast. There is a large drop in brightness at higher beam angles. The image to the right has undergone Beam Angle Correction to even out the brightness and bring out additional details at far ranges. (A high contrast setting was selected to bring out as much detail as possible from the far ranges.)

Slant range corrected images - without and with Beam Angle Correction.

Close-up of example target on the seabed

The images below are close-up details of one of the targets in the corresponding SRC image above. The image to the left has a lower contrast and a slight drop in brightness from top to bottom. The image to the right (w/BAC) has a higher contrast and more even brightness top-to bottom of the image.

Closeup of Targets from SRC images - without and with BAC.

2012/07/09: SonarTRX 12.1 released

The 12.1 release of all 3 product-versions is now available for download. Existing customers with an active maintenance agreement can request a download link by emailing support@sonartrx.com. Please see the Support page page for the latest release notes.

The new version of SonarTRX use parallel processing (w/multiple CPU's) to process multiple sonar channels simultaneously. The new Beam Angle Correction (BAC) feature allows for better quality slant range corrected images. In addition, the SI and LSS versions of SonarTRX now includes the same altitude tools as the full version of SonarTRX. (This allows for better control of the altitude used for slant range correction.)

2012/05/15: Position errors of marked targets due to heading differences

When marking targets visible on sidescan data from the Humminbird/Lowrance sonars, it is important to keep in mind that the boat heading (and normally the transducer heading) is not necessarily the same as the "Course Made Good" (CMG) based on GPS positions.

If the boat is pointing into the wind or strong current in order to stay on track, and the marked targets are far away from the track, this error may be large. The image below illustrates this:

Angle Errors

The boat (and the transducer) is pointing to starboard by 20 degrees relative to CMG.
The Brown image is calculated based on the assumption that the transducer is aligned with CMG.
The Blue images are based on a "pointing angle" of 20 degrees (i.e. you point the vessel 20 degrees into the wind/current in order to stay on track of the survey line)

In essence: When marking a target, keep in mind the heading of the boat relative to CMG and remember that the position of the targets may need to be adjusted for this heading error. If making the marks on the sonar during the survey, it is important to also make a mark at the track-line, since that is the "point of rotation" for this correction. The extent of the search area can then be increased to account for uncertainties in the transducer-angle.

If the boat is drifting while recording, the difference between CMG and the heading of the boat may be very large, and even completely flipped 180 degrees (...drifting backwards). In that case, if you targets are marked at a certain range, the marks may even be interpreted as being on the WRONG side, since there is no available information about the actual heading of the transducer. (i.e. everything is based on the CMG from the GPS)

The SonarTRX images can be corrected for a constant heading differences for a given batch of image-tiles. This is done from the Mosaic creation dialog.

It also contains several other usability enhancements.

One of these features is the ability to preview the sonar data, and define clips for later import by visually selecting the time-ranges, as shown in this screen capture:

Sample from the new SonarTRX View and edit interface

The image below illustrates the use of a large "Master Image" backdrop (in this case, a 36 Megapixels geo-referenced PNG image), combined with a single image-tile from the Down Imaging Channel of a Humminbird sonar recording. The Master Image above was generated by by SonarTRX based on 30 "traditional" SonarTRX image tiles (15 from each of the two sidescan channels)

2011/5/2: Recent SonarTRX improvements

When importing SonarTRX image tiles into GIS programs for assembly and merging into larger mosaics of the survey area, it is important to minimize any "seams" between adjacent image-tiles. The sample below illustrates recent improvements in that regards. The seams in the right side sample are barely visible.

Image Mosaic Improvements

The above sample images were generated with Manifold GIS, after importing 14 tiles from both starboard and port sidescan channels. No slant range correction was applied.

The sub-division of sonar data into image-tiles makes it easier to "mix and match" tiles from several passes over a survey area. As of version 10.5 of SonarTRX, the tiles can be cropped at a certain range, providing additional flexibility when assembling a mosaic of the survey area. The sample below illustrates this feature and how it can be used to avoid overlapping background imagery.
