Thx for the response.
Am I correct in my understanding that:
a radar station (either primary or secondary) transmits data to a computer. This computer converts the electronic pulse data/echo received from the radar antenna into a format called ASTERIX.
ASTERIX is the raw radar data and the primary usage is for archiving.
A filter, also a computer, filters the ASTERIX data and displays relevant info on the screen of the air traffic controller.
