Airspace situation monitoring technology is a key component of airspace management system, which is different from air and space surveillance systems such as ADS-B system. There are many factors affecting airspace state monitoring, among which the density of targets is closely related to the airspace situation. In the target airspace where aircrafts are relatively dense, the performance of various monitoring systems such as ADS-B and aviation radar is severely tested, which directly affects the accuracy of the airspace situation and the air and space situation in the target airspace.
