Well, not quite right, but close. There are a number of S Band Marine Radars in use, and available, worldwide. They are mostly used on ships LARGER than 1200 Tons, and used as Weather Radars, and Long Distance Position Fixing. Larry is correct, in that MOST Consumer and Small Ship Radars, are X Band, and your detector wouldn't see ANY of those. Bruce in alaska -- Bruce in alaska add path after fast to reply |

@netnews.worldnet.att.net: They are mostly used on ships LARGER than 1200 Tons, I figured most of these boys and girls were on plastic bubbleboats and didn't have 8MW air search radars aboard....(c; |

Back in the day, they would be used for Long Distance Position Fixing, as they had better Range than the fitted XBand Radars. GPS and Loran have taken over the Position Fixing Job, in modern Navigating, so SBand, which sees Atmospheric Moisture, much better than XBand, is used for that. Xband has much better Resolution than SBand, so it is used, to keep from running into other moving objects, inside the local path of the vessel. No Ship should be using Radar to keep from running into non-moving Objects, as GPS, Charts, and the Mark One Eyeball, should take care of that, and if not then the Master is sorely lacking in navigation skills. -- Bruce in alaska add path after fast to reply |
