Abstract
This work addresses the issue of calculating the power density (W/m2) and field intensity (V/m) distribution of NASA’s Deep Space Network (DSN) large reflector antennas in the Fresnel (near- to middle-field zone) as a function of the distance from the antenna and the off-axis angles. The calculation uses a simplified scalar method for radiation from circular apertures. The emphasis in this article is on the impact of the near- to mid-zone fields of DSN antennas on compliance with aircraft certification limits. The region of particular interest is the approximate range of 200 m to 30 km, which falls in the mid-field or Fresnel zone of the 34-m and 70-m antennas of the DSN.
