Study of passive aircraft surveillance radar using DTTB signal delay

The current Air Traffic Management uses various radar or radar like systems. However, the conventional Primary Surveillance Radar (PSR) have a high cost of the maintenance and the operation in comparison with usage. Recently, Multi-Static Primary Surveillance Radar (MSPSR) has attracted interest from the civil aviation research field. The MSPSR system is to use not just the conventional PSR signals, but also other radio waves, such as Digital Terrestrial Television, GNSS and cellar. Thus, MSPSR have the possibility to reduce the maintenance and the operation cost of PSR system. In this paper described the experimental results of aircraft detecting by using terrestrial digital broadcasting signal delay. It will be shown that the proposed calculation method is useful for detection of the aircraft.
