The invention relates to a production riser system wherein the riser, at the touchdown point, has a bottom flexjoint so that the dynamic motion of the riser is absorbed by angular excursion of the flexjoint and not by the interaction of the sag bend with the seabed. The base portion is generally rectangular. The processing module generates an outbound signal and a control signal to configure the integrated radar system. A wide variety of substrates can benefit from the technology disclosed.
