The systems and methods described here are about making radar radio waves travel better through different materials, like those found in the atmosphere or other substances. The radar system they propose helps reduce the bouncing back of radio waves when they pass through these materials.
To do this, a "matching layer" is designed using a special model. This matching layer is like a buffer between the radar system and the material the waves are passing through. By choosing the right material for this matching layer and putting it between the radar system and the material, the reflection of radio waves is reduced. This makes the radar system work better and reduces the amount of energy lost in the process.
