摘　　要：简述了圆口径地面站天线发射近区功率密度的计算方法。推导了圆口径均匀分布、锥削分布和高斯分布的圆口径天线近区功率密度的简化计算公式,并根据地面站天线旁瓣增益包络的要求,提出了一种快速估算地面站天线偏轴近区功率密度的简单方法。A method for calculating near region power density circular aperture earth station antennas is described briefly. Simple calculation formula of near region boresight power density is educed for circular aperture antenna with mean distribution, taper distribution and gauss distribution. A simple method for fast estimating earth station antenna off-boresight near region power density is put forward.
