Multi-Static Primary Surveillance Radar (MSPSR)


Multi-Static Primary Surveillance Radar (MSPSR) is an independent surveillance technology that uses a distributed transmitter and receiver architecture to detect aircraft, even when they are not equipped with cooperative surveillance systems such as transponders or ADS-B. We are researching how it could be used for separation services as part of future operations.


Today’s rotating primary radars require high volumes of spectrum and can also be negatively affected by wind farms, meaning we sometimes have to object to wind farm applications on the grounds of safety. MSPSR reduces impact on valuable mobile communications spectrum, mitigates against wind farm interference and reduces maintenance costs.


A collaborative project called PROVE has already successfully demonstrated that MSPSR based on DVB-T (TV) transmissions has the capability to provide a 3nm separation service. The technology is now being further matured for civil ATC use.


PROVE was conducted with Thales ATM UK and Roke Manor Research. Our work through SESAR is being conducted with Thales, Eurocontrol, DFS and DSNA.
