Certain electronic devices, while being radiated by external field can generate scattering signal, which can become interference for nearby radio-receiving apparatus in wide bandwidth. For measuring of parameters of the field, scattered by such non-linear objects, there is a necessity of calibration of radar measuring device. For this purpose a benchmark(standard) can be used. 

For example a passive non-linear reflector with determined effective scattering surface, capable to generate intensive scattering signal in a quite wide bandwidth or several reference non-linear scatters with a more narrow operational band for promoting measurements in a defined range.

This study proposes construction of standard non-linear reflector, used for calibration of broadband non-liner radar measuring device and describes calibrating procedure. Proposed construction is a kind of broadband antenna, known as “butterfly” antenna, connected to a tunnel diode. Optimal dimensions of the antenna are chosen basin on necessity to work in wide bandwidth. Equivalent radio engineering circuit of the standard is presented in the research and mathematic model is build. Basing on that mathematic model the numerical experiment is performed. The experiment is resulted in building of diagrams of amplitude and calibrating amplitude-frequency parameters of the standard in wide bandwidth. Presence of the extreme points at the diagrams proves possibility of applying of described construction of non-linear reflector as a benchmark (standard) for calibrating procedures.  Its applicability is justified both for radar measuring device equipped with combined transmitting and receiving antennas and for measuring device equipped with separated ones, which may have importance for experimental studies of spatial features of non-linear objects.
