Abstract
A multistatic radar system is provided for detecting and tracking targets moving in a surveillance area that includes: a radar transmitter and a plurality of radar receivers located in different positions in the surveillance area and processing means. The radar transmitter and the radar receivers are configured to obtain a GNSS-based time reference based on the GNSS signals received by the respective GNSS receiver. Each radar receiver is configured to determine, for each radar echo received by the radar receiver from a respective target, a corresponding distance-related information item based on the predefined transmission time and frequency pattern, the GNSS-based time reference and a respective reception time of the radar echo, and to provide the processing means with data indicative of the distance-related information items and the Doppler frequencies determined by the radar receiver, and reference times associated with the distance-related information items and the Doppler frequencies.
