The knowledge of beam pattem probability density function (PDF) plays a crucial role in target strength estimation when using indirect methods. The paper describes the theoretical and practical aspects of approximations applied in calculating the PDF of this deterministic function from a probabilistic point of view. The solution of differential equation presented in the paper leads to a unified approach to approximations and has a elear interpretation.
