*********************** CauchySAR_v1 - SAR Inverse Problem Solving via Cauchy Proximal Splitting ****************

---

This package includes the MATLAB source code for using the Cauchy proximal splitting (CPS) algorithm to solve a number of SAR imaging inverse problems including:

1) Super-resolution
3) Image-Formation
4) De-speckling
5) Ship Wake Detection.

Specifically, this package includes three folders:

1) images		: Stores images for the inverse problems examples.
2) examples		: Stores four scripts for each of the SAR inverse problems.

	2.1) CPS_ex1_superresolution.m
	2.2) CPS_ex2_imageFormation.m
	2.3) CPS_ex3_despeckling.m
	2.4) CPS_ex4_shipWakeDetection.m
	
3) source functions	: Stores the source functions below:

	3.1) ConfirmedHalflines.m        
	3.2) norm_visual_SAR.m            
	3.3) estimatePSF.m                
	3.4) radonT.m                     
	3.5) CauchyProx.m                 
	3.6) forwardOp.m                  
	3.7) rpBasicFarField.m            
	3.8) LoadSARDataRecons.m          
	3.9) generateSpeckle.m            
	3.10) rpFast.m                     
	3.11) bpBasicFarField.m            
	3.12) imageNormalize.m             
	3.13) rpFastFarField.m             
	3.14) bpFast.m                     
	3.15) inverseOp.m                  
	3.16) bpFastFarField.m
