RadExPro 2025.4 has formally been released. Here are the release note highlights;

• The 2D Kirchhoff Depth Migration module has been improved. The travel time computation step is now parallelized. In addition, we have implemented an option to compute travel times on a decimated grid to further accelerate the computation. Moreover, you can now precompute multiple versions of the travel times and select the desired one during the migration step. All travel time computation parameters are loaded from the travel time dataset. They are automatically updated in the module window after travel time dataset selection in the ‘Compute migration’ mode.

• In the Boulder Detection 3D/2D modules, we have added a new attribute: the maximum attribute value within each boulder. This value is saved as a separate column in the output ASCII table.
• If your license is time-limited, its validity period is now displayed in the status bar of the program main window.
• A couple of modules have been If your license is time-limited, its validity period is now displayed in the status bar of the program main window.
• A couple of modules have been transitioned to the new universal parameter style. These modules now offer full support for replicas and include standard export/import functionality. The affected modules are as follows:
  o 3C Orientation
  o Ensemble Equalization

A full list of updates, fixes and new features can be found in the complete release notes, see below.

Today marks a significant vote of confidence in the PinPointR’s quality and durability: ImpulseRadar has extended the antenna manufacturing warranty to five years.

The design ethos behind the PinPointR has proven to be exceptional. By combining advanced GPR electronics within a simple, robust, and reliable form factor, ImpulseRadar are able to stand behind its proven reliability.

Warranty Coverage:
Antenna: Extended to 5-year manufacturing warranty (up from 2 years)
Pushcart: Continues with a 2-year warranty coverage
Batteries, Cables, and Consumables (e.g., skid trays): 1-year limited warranty

RadExPro have recently updated their tutorial on Advanced Offshore High-Resolution Multichannel Seismic Processing. The Multiple Removal section now includes several new pages detailing the Curvelet Domain Subtraction technique. This method can enhance—sometimes significantly—the effectiveness of subtracting a multiple model from the original wavefield.

RadExPro Version 2025.1 boasts two new features to add to it every growing marine repertoire.

The Unaliased Fourier 2D Interpolation module conducts interpolation of 2D data in Fourier domain. Depending on the parameters and input data, this module can be used to regularize a 2D gather, fill holes in it (e.g., reconstruct missed shots on a common-channel gather or broken channels on a common-shot gather), or interpolate it onto a finer grid. For seismic streamers with changing receiver spacing, this module can be applied to create constant spacing. When interpolating/regularizing common-shot, common-receiver or common midpoint gathers, NMO can be applied before this module in the flow to decrease the probability of introducing aliasing into the interpolation result. The module has an antialiasing scheme and can, theoretically, reconstruct aliased data, so one may choose to interpolate such gathers without NMO to enable the interpolation of both reflected signals and various types of noise (for example, surface waves). It is an alternative solution to the existing Sparse F-K Interpolation with a different interpolation algorithm and additional capability for header interpolation.

The new module OBN Multi-Component Rotation function estimates the tilt and orientation angles of an OBN (Ocean Bottom Node) based on first-break energy polarization analysis and performs the corresponding rotations. If an OBN is not equipped with orientation sensors, the module can be used to compute and apply the necessary data rotation. Otherwise, it can serve as a quality control tool to verify the proper functioning of the orientation sensors. The module allows rotation of the X-component either toward the north or toward the source.
