## What it is
A collection of MATLAB code, simulations, and study notes on Synthetic Aperture Radar (SAR), InSAR, and PolSAR written by the author during graduate studies. It covers classic SAR imaging algorithms (RD, CS), Radarsat-1 data processing, InSAR scene simulation and interferometric processing, and PolSAR polarimetric calibration algorithms.

## Use cases
- learn SAR imaging algorithms like RD and CS
- simulate InSAR raw echo data for flat and conical scenes
- process Radarsat-1 data for SAR imaging
- study polarimetric SAR calibration algorithms like Whitt, Quegan, and Ainsworth
- find reference MATLAB code for synthetic aperture radar coursework

## When to choose
- you are a student or researcher starting out in SAR/InSAR/PolSAR and want worked examples with experiment reports
- you need MATLAB implementations of RD, CS, or polarimetric calibration algorithms for study or comparison

## When to avoid
- you need production-grade, maintained SAR processing software
- you require a license-clarified codebase for commercial use
- you expect updates or support, since the author has left the field

## Facets
- artifact type: learning-resource
- maturity: abandoned
- function: simulation, image-processing, data-science
- domain: education, tutorials
- platform: -
- tags: sar, insar, polsar, radar-imaging, matlab-code, rd-algorithm, cs-algorithm, polarimetric-calibration, radarsat-1, matlab
