Your video is of a radar, which specific radar is impossible to say with certainty, but quite possibly it is the JORN out of Australia. Some radars are easy to identify with relative certainty, others not so much.
Keep in mind that all signals that you see like this are not necessarily radar, or at least radars intended to track man made items like ships and planes, some might be sounders (specialized ionospheric radars).
You will often find that these radars often have no set frequencies, what you find them on today will not be what they are on tomorrow. They often hit around the same frequency ranges, but differing specific frequencies. These radars generally have azimuthal control but no elevation control, and ionospheric propagation (skip) varies greatly. The way these systems control what portion of the Earths surface they illuminate (and so the area they detect targets in) is by varying the frequency to take advantages of current, and ever changing, propagation conditions.
