Using GTEM Cell to Measure RCS of Electrically Small Scatterers

A new method of using gigahertz transverse electromagnetic (GTEM) cells to measure backscattering cross section (BCS) of electrically small scatterers is put forward in this letter. Compared to the traditional method of measuring BCS, the cost of this new method is low, the measurement process is simple, and the required sites are small. The correctness and feasibility of this method are confirmed by experimental results. This letter provides a completely creative method of BCS measurement and expands a new application area for GTEM cell.
