摘要
在2012年6月至2013年5月期间，在巴西SP的 o jossore dos Campos收集了1 Hz至9.4 GHz的电磁频谱测量数据。在这个地点，电磁波谱是由自然和人工来源产生的。利用手持探测器和紧凑型天线在两个频率范围(1hz至1mhz和1mhz至9.4 GHz)测量电场和磁场的强度。测量以扫描时间模式和分辨率带宽(RBW)的变化精度进行。频谱中的主要峰对应于7.8、14、20和33 Hz的舒曼共振，由电力线、无线电频率、导航无线电信标、移动电话和Wi-Fi系统、C和x波段雷达(地面站和飞机上)发射。
The electromagnetic spectrum from 1 Hz to 9.4 GHz near ground level in the region of São José dos Campos, SP, Brazil
In the period from June 2012 to May 2013 measurements of the electromagnetic spectrum from 1 Hz to 9.4 GHz were collected in São José dos Campos, SP, Brazil. At this site, the electromagnetic spectrum is produced by both natural and artificial sources. The intensities of the electric and magnetic fields were measured in two frequency ranges (1 Hz to 1 MHz, and 1 MHz to 9.4 GHz) with hand-held detectors and compact antennas. Measurements were performed in sweep-time mode and changing precision in the resolution bandwidth (RBW). Main peaks in the spectrum correspond to Schumann resonances at 7.8, 14, 20 and 33 Hz, emissions by power lines, radio frequencies, navigational radio beacons, mobile phone and Wi-Fi systems, C- and X-band radars (ground stations and on board aircraft).
