    Estimado Hernan


    Una duda, sabes las características del APG-83, en especial el rango de cobertura en grados...¿?

    Esto oficial de Lockheed Martin sobre el APG-83 ofrecido a la India:

    The AESA radar tracks and maintains at least 20 air-to-air targets within scan volume (±60-degree cone). When the
    radar is commanded to search targets with a specified search pattern (e.g., fixed number of elevation bars and
    azimuth wscan width), the radar can still track targets outside of the specified search pattern using extended volume
    target track capability

    Therefore, only Taiwanese, Singaporean and South Korean contract to upgrade 353 "Falcon" is already estimated at 7.1 billion dollars, not considering the possibility of starting similar work to re-equip the air forces of Poland, Denmark, Turkey etc. Which gives prospective airborne AESA radar AN/APG-83 SABR multi-purpose fighters F-16A/B/C/D. first, it is a much greater range of detection of air targets: an object with RCS of 2 m2 can be detected and take over maintenance on the removal of 150-160 km and captured at a distance of about 125 km, and are Accompanied by much more small targets than normal radar with a slotted antenna array (SAR) AN/APG-66. Modern high-performance computing framework AN/APG-83 SABR allows each AFAR MRP (or MRP group) to work on their own frequency, simulating the complex radiation pattern in the LPI mode ("low possibility of signal interception") for legacy SPO type "Birch".

    AFAR also has significantly higher noise immunity and resolution when scanning water/sea surface in synthetic aperture mode (SAR). Station of the previous generation AN/APG-68(V)9, though a mode SAR, the resolution is very ******** and does not allow to classify small-size ground targets, on the basis of their geometric features.Second, the AN/APG-83 has a much higher bandwidth (in the SNP at least 20-30 VAC), target banalnosti (8 simultaneously engaged targets), as well as hardware adaptation for use of the transceiver modules AFAR as emitters of radio interference. The last option has also found use in radar AN/APG-81 fighter the 5th generation F-35A. Thirdly, as each radar with active AESA, AN/APG-83 has a significantly greater reliability (time between failures).

    Por eso tambien se irìan teòricamente los APG-68(V)9 (de los B50) que son radares relativamente jòvenes.

    Al parecer, la ganancia con cambiarse desde estos es sideral -3-5 veces màs confliable en terminos de MTBF, divisiòn de trabajo de los grupos de mòdulos emitiendo en distintas direcciones y en LPI, menos jammeable, +-2 veces en alcance de track para blancos aèreos (track! a 125 km te da tiempo para una mejor identificaciòn/verificaciòn y sacarle todo el rendimiento a los AIM-120 C7), resoluciòn SAR 0,3 m (1 ft) vs 0,5 m (imaginarse hacerla desde un APG-66 que no tiene SAR HR). La tecnologìa esta avanzando muy ràpido... mucho màs rápido que antes.

    Bueehh, hagamos memoria de la relación con ViaSat, del 2015.


    The MIDS JTRS terminal is a four-channel software-defined radio that delivers existing Link 16 tactical networking and situational awareness with concurrent multi-netting-4 and tactical air navigation (TACAN) functionality.

    Data Link Solutions won a $478.6 million MIDS JTRS production contract in mid-June, and ViaSat won a contract of identical value in late May. The total value of these MIDS JTRS production contracts is $957.2 million

    The MIDS JTRS terminal has three channels for future growth, including JTRS advanced networking waveforms such as tactical targeting network technology, multifunction advanced data link, intra-flight data link, and other advanced networking waveforms.

    The system is a line-of-sight radio system for collecting and transmitting broadband, jam-resistant, secure data and voice across a variety of air, sea, and ground platforms.

    The contract encompasses MIDS JTRS purchases for the U.S. Navy, as well as the governments of Austria, Chile, Finland, Israel, Jordan, Japan, Kuwait, Malaysia, Morocco, Oman, Pakistan, Qatar, South Korea, Saudi Arabia, Singapore, Sweden, Switzerland, Taiwan, Thailand, United Arab Emirates, Australia, Canada, New Zealand, United Kingdom, NATO, and all NATO nations under the Foreign Military Sales program.
