Study on GNSS‐R multi‐target detection and location method based on consistency checking
The use of GNSS reflected signals to carry out passive detection of space targets is an emerging technical field. Unlike the traditional GNSS‐R in large‐scale environments such as oceans, vegetation, ice and snow, it is required to identify different ...
