SAR Imaging
Geometry-aware teaching model — acquisition geometry → raw echo → range compression → focused image
Guided presets
Range blur starter
Low bandwidth to make horizontal blur immediately visible.
Azimuth blur
Long antenna to worsen stripmap azimuth resolution.
Sharper reference
Short antenna + wider bandwidth for a tighter focused image.
Default preset: low bandwidth makes the range-resolution effect easiest to notice first.

Parameter insight
Adjust bandwidth, antenna length, slant range, and velocity to see how the geometry and image change together.
