Abstract :
The boundary value problem (BVP) is reduced to a 1-D integral equation of the 1st kind and then to an ill-conditioned matrix equation. A new iterative method is proposed for such equations´ solution, which produces a robust and adequate solution. This solution is compared with the genetic algorithm solution and good agreement is obtained. A strong backscattering for a 1° grazing angle is revealed from a resonant-sized foaming-like ocean wave, that is comparable in order with radar “sea-spikes”
