CASSIDIAN’s newly developed TRS-4D Naval Radar opens a New Dimension in Sensor Technology

  • Unprece­dent­ed capa­bil­i­ties of threat detection
  • Improv­ing mis­sion suc­cess and plat­form survivability

14 Sep­tem­ber 2011 – Cas­sid­i­an, the defence and secu­ri­ty divi­sion of EADS, intro­duces a new gen­er­a­tion of naval radars into the mar­ket with unprece­dent­ed capa­bil­i­ties for the sur­veil­lance of sea areas and coun­ter­ing even asym­met­ric threats. TRS-4D is Cassidian’s inno­v­a­tive step from con­ven­tion­al radar into a “new dimen­sion” of oper­a­tional capa­bil­i­ty. TRS-4D enables ships from patrol ves­sels to frigate size to exert the dif­fer­ent detec­tion tasks of a ship-borne medi­um range sur­veil­lance and tar­get acqui­si­tion radar, in blue waters and also in com­plex lit­torals with high tar­get den­si­ties. It per­forms faster, more accu­rate and against a wider scope of tar­gets than in the past. 

The new radar is based on a unique sys­tem con­cept. It comes with a rotat­ing anten­na based on the lat­est Active Elec­tron­i­cal­ly Scan­ning Array (AESA) tech­nol­o­gy giv­ing the capa­bil­i­ties of over­laid mechan­i­cal and elec­tron­ic scan­ning. The result is an unmatched detec­tion per­for­mance. This approach pro­vides navies and coast guards with the ben­e­fits of sol­id-state based AESA tech­nol­o­gy, which up to now has been avail­able to high­ly expen­sive sys­tems only. Cas­sid­i­an makes this tech­nol­o­gy afford­able and com­pet­i­tive also for medi­um-sized Sur­veil­lance and Tar­get Acqui­si­tion Radars. Unlike oth­er avail­able radars on the mar­ket, TRS-4D is the first sur­veil­lance radar to make full use of the advan­tages of simul­ta­ne­ous mul­ti­ple beams based on AESA tech­nol­o­gy. A non-rotat­ing vari­ant of TRS-4D with four fixed array pan­els is already under pro­duc­tion for the new F125 frigates of the Ger­man Navy. 

“While cap­i­tal­is­ing on high oper­a­tional avail­abil­i­ty in extend­ed mis­sions, our new radar also offers improved ship sur­viv­abil­i­ty”, explains Elmar Com­pans, Head of the Sen­sors and Elec­tron­ic War­fare Busi­ness Line of Cassidian. 

AESA tech­nol­o­gy and, there­fore, elec­tron­ic beam steer­ing, enables the radar to ful­fil sev­er­al tasks at the same time while increas­ing the detec­tion capa­bil­i­ty sub­stan­tial­ly. The unique detec­tion per­for­mance derives from a mul­ti­tude of Cassidian’s Trans­mit- and Receive Mod­ules, based on the most recent Gal­li­um­Ni­tride (GaN) tech­nol­o­gy. GaN holds unique elec­tron­ic char­ac­ter­is­tics like high pow­er added effi­cien­cy and allows for very effi­cient indus­tri­al pro­duc­tion process­es. Cas­sid­i­an is the Euro­pean leader in this technology. 

Cas­sid­i­an, an EADS com­pa­ny, is a world­wide leader in glob­al secu­ri­ty solu­tions and sys­tems, pro­vid­ing Lead Sys­tems Inte­gra­tion and val­ue-added prod­ucts and ser­vices to civ­il and mil­i­tary cus­tomers around the globe: air sys­tems (air­craft and unmanned aer­i­al sys­tems), land, naval and joint sys­tems, intel­li­gence and sur­veil­lance, cyber secu­ri­ty, secure com­mu­ni­ca­tions, test sys­tems, mis­siles, ser­vices and sup­port solu­tions. In 2010, Cas­sid­i­an – with around 28,000 employ­ees – achieved rev­enues of € 5.9 bil­lion. EADS is a glob­al leader in aero­space, defence and relat­ed ser­vices. In 2010, the Group – com­pris­ing Air­bus, Astri­um, Cas­sid­i­an and Euro­copter – gen­er­at­ed rev­enues of € 45.8 bil­lion and employed a work­force of more than 121,000.
