The paper presents an approach to modeling the secondary emission field, based on the Huygens-Fresnel method. Various methods for simulating the secondary radiation field are briefly reviewed, and their key characteristics are given. Features of the software implementation of the algorithm for synthesizing signals reflected from objects of a complex spatial configuration and obtaining on their basis radar range portraits are considered. The description of the modeling process is divided into stages, which makes it possible to trace the structural and logical connection between the methods and actions performed in the course of the modeling of the secondary radiation field. The key feature of this approach is the use of depth maps (Z-buffer) to determine the visible areas of the irradiated object. Also, some methods of improving the performance of computations are described, which is especially important where it is required to obtain a large number of radar range portraits.
