Excerpt from Electromagnetic Airframe Penetration Measurements for the Faa Bombardier Global 5000

Figure 1. Airframe shielding measurement system (receiving side). The reverberant nature of the airframe permits the reception of both horizontally and vertically polarized signals.approximately mhz to 4 ghz. A reduced frequency spacing is necessary to avoid problems due to aliasing. Prior to connecting the cables to the antennas, a calibration of all channels was performed to remove systematic transmission effects due to cabling, switches, and the frequency and phase variations of the optical transmission link. This procedure calibrates the system with respect to the input of the transmitting and receiving antennas. Three nist-developed ultra wideband T EM horn antennas were used: two m antennas on a tower located outside of the aircraft, either to transmit horizontally and vertically polarized fields, and a more compact 36 cm tem horn located in a pre-selected aircraft compartment to detect energy coupled into the airframe. For the higher frequency bands, three commercially available drg antennas were used: two on the same transmitting tower located outside of the aircraft to transmit horizontally and vertically polarized fields, and a drg antenna located in the same preselected aircraft compartment to detect energy coupled into the airframe. The frequency data were digitized and transferred to a laptop computer for subsequent data analysis and signal processing.
