Target InterceptTarget Intercept enables the radar operatorto plan and implement an interception of atracked target. This is particularly useful inmaritime interdiction operations (MIOPs).

Helicopter ApproachThis feature provides the ability to set up anapproach sector on the screen, which isespecially valuable in conditions of poorvisibility. The radar operator is able to checkthe status of the helicopter’s approach andoffer guidance to the pilot. And, theapproach sector may be set up on ownship oron any tracked target.

Freeze FrameThis feature is used whenever it is necessaryto impose radar silence. Once the operatoractivates this function, the radar displayshows a still image of the radar situationimmediately before radar silence was ordered.The operator can activate this functionlocally or it can be imposed remotely.

Station KeepingIn inclement weather or at night it is oftendifficult to maintain station on surroundingvessels. The Station Keeping feature allowsthe operator to define a sector for everynearby vessel so he can immediately see ifany vessel has moved from its correctlocation.

Advanced Index LinesIndex lines are often used for blind pilotingoperations. Sperry Marine’s navalized displayallows up to 15 index lines to be displayedsimultaneously in groups of five. Theoperator can clip the lines to the exactlength required in order to reduce clutter. Inaddition, these lines may be prepared inadvance and stored on a memory card forfuture use.

Range YardsThe navalized display offers the operator achoice of the standard radar distance units ofnautical miles, kilometers or statute miles orof yards. The units selected will be setduring commissioning.

Tactical DisplayThe BridgeMaster E Tactical Display is thefirst marine radar system in the world that isable to display inputs from two totallyasynchronous radar heads simultaneously inthe same video circle. This advanced radarsystem combines unique naval features withpowerful configurations and options that farexceed those of its predecessor.

Main FeaturesAsynchronous Secondary RadarInputThe BridgeMaster E tactical display can showinput from a totally asynchronous radar.This second input can be from either aBridgeMaster E transceiver or, in someinstances, from another manufacturer’sradar. Any combination of radars can beused, e.g., two X(I)-band radars or an X(I)-band and an S(E/F)-band or an X(I)-bandand an RRB. Using a second input fromanother BridgeMaster E radar allows theoperator to control both radars through a

single display. Plus, the operator can tracktargets from either radar, and the softwareensures that a target will only be trackedonce.

600 Knot Target TrackingThe BridgeMaster E tactical display is idealfor the detection, tracking and interceptionof fast moving targets. It can track targets atspeeds of up to 600 knots. And, targetmaneuvers can move up to 4G, dependingon target range, antenna rotation rate andlocal clutter conditions.

Sector TransmissionThis feature allows the operator to define twosectors in which transmission is to take placewhile radar silence is maintained on allother bearings. Each defined sector willremain stable with respect to north even ifownship alters course. This ability isespecially useful when radar silence isrequired over a particular arc, but radarwatch is needed on a bearing of interest.

Convoy SectorsThis feature allows the operator to displayNATO standard convoy sectors using eitherXY(4W) or polar grids for convoy/battlegroup position control. The grid can bereferenced to the guide ship, which could beeither ownship or a selected tracked target.With the XY grid option the operator is ableto rotate the grid when the convoy axischanges. If ownship or other vessels deviatefrom their required station, the grid providesthe operator with early notification.

Weapon System InterfacingThe BridgeMaster E tactical display caninterface with other shipboard equipment,receiving input from a weapon system or anight vision system via an optionalcommunications board. It can also outputdata on designated tracked targets to othersystems, providing range and bearinginformation. That data can be used to alignthe night vision or weapon system to asuspicious contact.

Additional Range ScaleRealizing the need for long-rangecapability, the tactical display is equippedwith an additional range scale of 192nm.This feature is particularly useful whenused in conjunction with a long-rangeradar system to provide a secondary inputto the tactical display.

Navalized Display CapabilitiesAll features of the BridgeMaster Enavalized display are included as standardon the tactical display. The one exceptionis the station keeping feature which isreplaced on the tactical display with theConvoy Sector.

Other Features:The tactical display includes Bearing tothe Closest Point of Approach (BCPA), anda training simulator that providesscenarios to be used for operator training.

BridgeMaster E Transceiversoffer a number of optionsAll transceivers in the range use standard commercialfrequencies so potentially hostile targets see them asmerchant rather than military radars.

The transceiver acts as a centralized distribution forradar synchronization. It accepts external triggerinput (200Hz-10KHz) that synchronizes itstransmission with other systems. Three independentadjustable pre-trigger signal outputs, which may beused by ownship’s EW systems, avoid damage when aradar pulse is transmitted.

The BridgeMaster E naval transceiver has two positiveand two negative radar video outputs, so that thevideo is available to other systems without the needfor additional signal inversion circuitry. There arealso two sets of bearing data output in serial format(heading marker and incremental azimuthinformation).

The wide range of inputs and outputs allowsBridgeMaster E radars to interface quickly and easilywith other onboard systems thus reducing thecomplexity of the system and associated costs.
