Out of the box the ASP.NET menu control doesn’t support setting a Target on a menu item.  You can easily add  support for this by adding a target node to the site map xml and then adding a event handler to set that on the menu item at data binding time.

So for example my siteMapNode would look like this with the target specified:

<siteMapNode title="New Property" description="New Property"  url="Manage/Property/NewProperty.aspx" target="_blank" />

Then on the menu itself you would add an event handler to handle the MenuItemDataBound event.  It would look like the following:

protected void Menu1_MenuItemDataBound(object sender, MenuEventArgs e)
        {
            SiteMapNode menuNode = (SiteMapNode)e.Item.DataItem;
            if (menuNode["target"] != null)
                e.Item.Target = menuNode["target"];

        }
