A movable space electromagnetic environment determination and analyzing method is to integrate all the omnidirectional antenna, electromagnetic field-intensity meter, geographic space position indicator, electromagnetic field-intensity meter data converting card, space electromagnetic environment base data memory, geograhic information system onto a movable carrier, such as vehicle so as to realize movable determination and analysis of space electromagnetic environemnt. By means of combining the measurement and analysis of space electromagnetic environment and the geographic space positioning technology, the basic data of space electromagnetic radiation distribution is collected dynamically, processed in geographic information system and display in the electronic map mode. |
