Detailed Description

I would like to know if there are any specific papers or related content to refer to for this Wave Propagation Model. I want to develop a Synthetic Aperture Radar model using Omniverse Radar Extension and generate corresponding imaging algorithms, so I want to know the details of Wave Propagation Model.

Thanks for your interest in the Omniverse Radar Extension and the Wave Propagation Model (WPM).

I understand you’re looking for more information to develop a Synthetic Aperture Radar (SAR) model using the extension. To clarify, the “WPM” referenced in the context of the WpmDmatApproxRadar model within Isaac Sim uses an internal NVIDIA wave propagation model, which is not currently exposed for customer access or modification.

The WpmDmatApproxRadar model provides a way to simulate radar returns with enhanced fidelity due to the wave propagation, but it’s important to note that this is not a Synthetic Aperture Radar. You’re essentially working with our existing radar model and its exposed parameters and outputs. At this time, directly implementing a new class of radars, such as a full SAR simulation with custom wave propagation, is not supported within the current framework.
