Distributed GNSS interference effectiveness evaluation method

The invention discloses a distributed GNSS (Global Navigation Satellite System) interference effectiveness evaluation method, which comprises seven steps and can accurately give spatial distribution characteristics of distributed GNSS interference signals. According to GNSS interference radiation source signal characteristics deployed on different nodes, on the basis of obtaining interference radiation source information, interference signal characteristic changes of each interference radiation source from transmitting to receiving on a whole electromagnetic wave propagation link are completely considered, and attenuation estimation of electromagnetic waves in a channel propagation process is realized through a radio wave propagation model. And accurate evaluation of the GNSS interference coverage range is realized by combining the self anti-interference characteristic of a carried satellite navigation system module or equipment. 本发明所公开了一种分布式GNSS干扰效能评估方法，包括七个步骤，该方法能够准确给出分布式GNSS干扰信号的空间分布特征。根据部署于不同节点上的GNSS干扰辐射源
