Abstract. The automated laboratory bench for objects scattered characteristics measuring in the frequency range from 4 to 15 GHz is developed and approved. The main elements of the stand are the vector network analyzer, the broadband antenna (1-17 GHz) and the turntable. To suppress reflections from the walls, ceiling and floor of the range and auxiliary equipment the time domain gating of the reflected signal and subtraction of the background are used. The processing algorithm for reflected signals is described and applied. The series of three transformations of the received signal is performed: from the frequency domain to the time domain, the selection of the time gate width and position, the transition from the time domain to the frequency domain. The experiments series of comparing the theoretical values of radar cross-section (RCS) with measured for some spheres are performed. The analysis of the measurement data revealed the features of the stand. Firstly, the duration and parameters of the time gate for the object under test and the standard should be the same. Secondly, the transformation specificity does not allow to use the beginning and end of the all measured frequency band.

The RCS of the 4 plastic spheres with a diameter of 300 mm with the conductive coating and the same sphere covered with silver were measured. High repeatability of the scattering characteristics of five spheres is noted. Monostatic RCS of angular reflectors and metal plates in C- and X-bands are measured.

Key words: scattering characteristics, calibration, radar cross-section (RCS), time domain, window Fourier transform.
