Description
technical field [0001] The invention relates to the field of communication technology, in particular to an electromagnetic emission source positioning system and method. Background technique [0002] The demand for radio direction finding equipment in the military has led to the rapid development of wireless positioning technology. The traditional positioning technology research is to use two or more fixed direction-finding stations to network for rendezvous positioning. This positioning and direction finding technology can solve many practical problems in the process of use, but due to the influence of various factors, there are certain errors in this measurement method, which cannot achieve what people imagine. The approximate position of the target can be measured, but this position is an area, and the exact position cannot be determined. Therefore, it is of great value to conduct further research on radio technology and improve the accuracy of radio direction finding i...
