This tower isn't marked on the OS map, but it has been here since 2005. It is apparently run by the Met Office. It is certainly high enough to get a good view of the Thames Estuary, and indeed much of North Kent. There is an article about it here http://www.metoffice.gov.uk/olympics/doppler-radar-and-london-2012 and here http://www.metoffice.gov.uk/media/pdf/j/h/Fact_sheet_No._15.pdf
