Modern trends in radioelectronic technologies require the creation of lightweight electromagnetic scatterers with compact dimensions. This is due to the need to reduce transportation costs, simplify installation and maintenance, and increase the reliability of structures under environmental influences. Corner reflectors are typical examples of such structures, which are quite heavy and large. To solve this problem, it has been suggested to form sparse structures by optimal current grid approximation. However, its effectiveness has not been confirmed experimentally.

The aim of the article is to investigate the effectiveness of approximating scatterers with optimal current grids through modelling and measurement.

The measurement results showed that sparse structures have scattering characteristics comparable to the original wired grids in the main direction, while achieving a mass reduction of up to 1.7 times for a wired grid dihedral corner reflector and 1.8 times for a square wire grid. The measurement results showed a good match between the characteristics of the monostatic radar cross section of the sparse and original structures, especially in the main lobe region.

The optimal current grid approximation allows the development of lightweight scatterers, and the experimental data obtained confirm the promise of its application.
