BridgeMaster E Radar
180, 250 and 340 Series of Marine Radars

A Tradition of Innovation...

The Decca BridgeMaster E series of type approved radars continues the tradition of innovation well established by Decca radars over the last fifty years. BridgeMaster E is designed to offer an unparalleled choice of configurations and options to meet the requirements of every type, size and class of vessel including highspeed craft, whether it is a new build or retrofit.

...And Reliability

BridgeMaster E has been subjected to the equivalent of 23 years of operation at sea during its development to ensure that outstanding reliability is yet another standard feature of an already outstanding radar.

BridgeMaster E 180

Unique Clutter Suppression

Even the most basic models include clutter suppression capabilities unequalled in other radars, but with BridgeMaster E there is the option of fitting a revolutionary new clutter suppression system called Vision. It provides the first true hands-off clutter and gain control capability.

Vision allows the operator to leave the radar in automatic clutter suppression mode even when close to land and totally eliminates the need to adjust radar gain as the operator changes range or pulse length. The operator is left free to concentrate on what matters most and not have to worry about radar settings.

Choice of MMI and Fast, Simple Operation

Every radar operator has a preferred method of controlling the radar. The Decca BridgeMaster E allows everyone to fit the Man Machine Interface (MMI) of his or her choice. All BridgeMaster E radars may be fitted with either a joystick or a trackball and there is an optional dedicated keyboard incorporating the fundamental radar controls. In the kit form radars the control panel may also be mounted remotely to assist with installations where space is at a premium. The kit form variants simplify installation where a customer wishes to build his own consoles for integrated bridge applications.

BridgeMaster E with Vision provides a clear
at-a-glance threat assessment in all weather conditions.

Target Tracking

ARPA and ATA (Automatic Tracking Aid) versions of the BridgeMaster E have the ability to track up to 40 targets simultaneously at relative speeds of up to 150 knots and are approved to the latest specifications for these types of radar. Data on all tracked targets is output to be displayed on electronic chart systems or to provide information to other shipborne systems such as voyage data recorders.

Targets may be acquired manually or by using the annular and polygonal automatic acquisition zones. The two conventional annular zones are of variable depth and provide protection over any arc up to and including a full circle around own ship. The polygonal zones can be drawn to virtually any shape and are particularly useful for shore based or other stationary applications.

When target tracking, the operator is able to display full target data on any chosen target or CPA/TCPA data on six selected targets. The six targets may be selected manually by the operator or automatically on the basis of CPA or range.

The basic EPA (Electronic Plotting Aid) version complies with IEC 60872-3 and has the ability to plot up to 10 targets simultaneously.

Radar Maps

The radar maps used with all BridgeMaster E radars are constructed by the operator in a multi-layer format allowing the operator to select the information to be displayed on the radar screen. In addition, the colors and symbols, which are standard ECDIS symbols, comply with the requirements of the IEC specification for mapping radars. Map data is automatically aligned using the navigation input or to a known fixed point.

The maps may be used alone or built into folios enabling the maps for whole voyages to be pre-selected so that the operator knows that the correct map will always be on-screen without the need to make any changes. On most models the maps and folios are stored on memory cards thus providing essentially unlimited storage. On most of the basic models map storage is internal.

Map construction may be by means of the radarsí own controls or by accepting maps constructed within an electronic chart system (ECS). The ECS and radar can either be part of a complete integrated bridge system or simply interfaced with one another.

Navigation Data

The Decca BridgeMaster E radars accept navigation data directly from suitable navigation sensors or from an electronic chart system. In addition to own shipís position and cursor latitude and longitude, the radar is able to display a voyage plan thus providing the operator with an immediate indication of whether own ship is on track or not. This feature is particularly valuable for stand alone radar installations where an ECS is not available.

The number of legs of the plan displayed depends upon the type of navigation sensor in use. With a sensor supplied by Sperry Marine, the radar will display the last waypoint and the next five waypoints thus showing the current leg, the next four legs, time and distance to go to the next waypoint and off track distance.

2- or 6-Way Interswitching

Of increasing importance on larger vessels and, in particular cruise liners and ferries, is the ability to interswitch multiple transceivers and displays. The BridgeMaster E series includes 2-way and 6-way interswitch options. The 2-way allows two transceivers and up to four displays to be switched whilehe 6-way allows switching of up to six transceivers and six displays. In both cases the entire radar configuration can be set up from any of the displays. For security the interswitch may, if required, be configured to limit interswitching to local control after the initial setup has been carried out. The interswitch status may be seen at any time through the operating menu.

BridgeMaster E allows the operator to select the screen
most appropriate to ambient light conditions.

Both interswitches will handle any combination of X and S band, transceiver power, display size, ARPA and non-ARPA, transceiver aloft or below. The BridgeMaster E interswitching capability provides total flexibility.Communications between the transceiver and display are serial which greatly reduces the amount of cabling needed and, because the performance monitors are all built in to the turning unit, there is no longer a need for separate installation kits. This minimizes cabling, simplifies installation and reduces costs.

Commissioning has been greatly simplified by introducing full screen menus for use during set up which take the commissioning technician through the process step by step. This ensures that everything is done quickly and correctly thus saving time and reducing cost.
