Mectron MAR - 1 The Mectron MAR - 1 is a tactical missile that fires from Air to surface . It ' s Anti - radiation from medium range , with guidance liability radar with multiple bandwidth options to attack systems air defense based on land or on sea platforms . History . In 1998 The program was started to develop an anti - radiation missile to equip the aircraft A - 1 ( AMX ) Of FAB And is expected to 2008 the end of its development . From the outset the program was conducted by CTA ( General Command of Aerospace Technology ) , along with the company Mectron Also of Sao Jose dos Campos , And is currently in testing phase . According to the FAB disclosure , would have performed tests of the separation with the aircraft A - 1B GEEV ( Special Group Flight Test ) CTA . A simulated scenario analysis showed that the search head of the MAR - 1 is able to detect a radar low power ( in the case of an officer shot " Sky guard " ) at distances greater than 500 km . During this stage of development where it is , it was found that one of the limitations to the use of MAR - 1 is the definition of distance - aircraft radar , a parameter essential for a successful launch . This may have led developers to reassess their concepts . A major difficulty encountered was the lack of a platform girométrica national ( navigation system that " flies " the missile while it seeks the target during their flight ) available for the missile . Such technology is susceptible to embargoes for political and strategic countries that dominate . This required a project , starting almost from scratch , a block Girométrico Miniature Fiber Optic with three orthogonal axes to provide the on - board computer necessary information from the accelerometers , ensuring the precision missile . The design of this subsystem was funded by FINEP and conducted by IEAC ( Institute of Advanced Studies CTA ) And Mectron . Apparently it was completed . Another obstacle arose in 1999 when the Brazilian government attempted to make a purchase of spiral antennas and some other systems for the development of search head SEA - 1 in a manufacturer Las Vegas But the U . S . government vetoed the purchase claiming that " it is interesting to defend American in Brazil to introduce anti - radiation weapons in this region . " Faced with this obstacle , the CTA was seen with only one alternative : to develop locally the search head . This subsystem was developed and then tested with simulators emissions of TS - 100 + Excalibur Systems ( 0 . 5 to 18 GHz ) HS - 125 aircraft and the Flight Test Division of the CTA , we know even that has been studied by FAB installation of sensors in similar patrol aircraft P - 95 . It is likely that two heads are being developed to search for the missile , each for a certain range of frequencies from radar targets . They could be exchanged under the radar to be attacked . Initially it was hoped that the MAR - 1 were derived from the MAA - 1 Piranha , With necessary adjustments on the sensors and look similar to American AGM - 122 Sidearm , Which proved wrong when the disclosure of the first images of the missile . Its proximity fuze was ( or is being ) developed by the company Opto Electronics of San Carlos which also participates in the program CBERS in which will be responsible for manufacturing the camera MUX for satellite CBERS - 3 able to generate images of 20 meter resolution , and the development of night vision goggles ( NVG ) to Brazilian Army as well as lenses , mirrors and proximity fuze for a missile MAA and MAA - 1B . The scope that had been published in the specialized press , which gave figures of 25 km for a launch to 30 , 000 feet , Mectron states : " This is totally out of reality , are given an aerodynamic study that were not updated . The current range , demonstrated in tests , is much , much larger than this , and we will improve it further . To be able to have an idea , recently performed a test with a new engine that was so powerful it melted the exhaust nozzle and the rear portion of the missile , so we had to redesign everything . Now , a real number set and I can not provide . It ' s confidential . " According to Brigadier Bueno , the Aeronautics several countries have already requested information on the missile . The MAR - 1 will be employed in the context of war electronics , due to suppression of enemy air defense .
