Maritime moving target detection technique for passive bistatic radar with GNSS transmitters
The paper puts forward a moving target detection technique for passive bistatic radar system based on GNSS signals for maritime surveillance applications. If from one hand navigation satellites are extremely attractive as opportunistic sources for passive radar due to their global coverage and the availability of multiple satellites, on the other hand they provide a restricted power budget. To strengthen the target energy sufficiently to allow its detection, observation time has to be increased up to several tens of seconds.
