Abstract :
In this work, LASSO formulation, which is one of the compressed sensing techniques, is used as a method of SAR image reconstruction. Simulations on the real SAR images are performed in order to analyze the effect of the τ parameter in LASSO formulation to the formed SAR imagery. Formed images are compared. A parameter, derived from signal to noise ratio and cross correlation, is suggested to robustly select the sparsity limit parameter τ.
