Abstract :
A novel method to solve ill-posed problems is presented with a brief mathematical introduction. The method generates ℓ1 solutions that have few strong components in contrast to ℓ2 solutions with minimum energy. The method is compared with ℓ2 method using numerical and at-sea data with various numbers of samples and with background noise levels.
