Sample Radar data in ASTERIX Cat 240 format

As well as producing radar output in the colossus network protocol, Navtech Radars can be configured to produce a radar video output in ASTERIX Cat 240 format, as described on this page.

The network-capture recordings below are in pcap format and can be played back with a packet replay tool such as this one.

The recordings were made from a radar mounted at approximately 51° 45.246'N, 1° 20.988'W with “Radar-North” on a bearing of 262°.

In the recordings a school of one-person sailing dinghies were moving within the radar’s field of view, at distances up to ~600m from the radar, as shown in the photograph below. Note that the four files attached Note that although the four files accessible below were recorded on the same occasion at the same location, they are not contiguous.
