RFSS is a common test method in the research and development of radar guidance systems, which overcomes the problem of the large cost of the field test to a certain extent. With the development of radar technology, the evaluation of hardware in the loop RF simulation error needs to be more accurate. This paper summarizes the current research, mainly focusing on simulation error analysis, near-field error and near-field correction, expansion of simulation object and suppression of simulation error. At present, most studies focus on azimuth error and pitch error respectively, but do not take into account the correlation of the errors in these two different angle domains. Or only the root mean square of the amplitude of the two-dimensional angle error is considered, without considering the directional distribution of the angle error.

A dual-band dual-polarised nested Vivaldi antenna (DBDPVA) is proposed in this study. The antenna consists of two orthogonal dual-band nested antenna elements. The dual-band nested antenna element is achieved by nesting a 2-8 GHz double-slot section outside of an 8-40 GHz double-slot section on a common substrate. The dual-band nested antenna element is designed through parametric studies. To realise dual-polarised radiation, the feeding networks of the horizontal element are lengthened, and two complementary slots are cut in the substrate of horizontal element and a vertical element to arrange them in orthogonal crossed form. The measured −10 dB impedance bandwidths (S11) of the 2-8 GHz section and 8-40 GHz sections are ∼2-8 GHz and 8-40 GHz. The antenna elements have similar radiation characteristics after the crossed form arrangement. The measured maximum gain is higher than 4.6 dBi at 2-40 GHz and around 10 dBi at 6-35 GHz. The DBDPVA can be used in radio-frequency simulation system to expand the bandwidth and polarisation diversity of the system.
