DS-HES-S Radio Altimeter Simulator (Standard Case)

  • DS-HES series aircraft radio altimeter is a photoelectric delay system that was specially developed for various radio altimeter simulators’ productions, measurements, and maintains. The systems depend on the technology of the fiber-optic delay line, using fiber-optic lines as the carrier, and the feature of light delay to simulate RF microwave signals’ space transmission distance. In addition, with this technology, the systems can simulate and measure different heights’ transmission.
  • Compare with traditional SAM(surface acoustic wave) delay line systems, DS-HES series products have more advantages such as a wide working frequency band, high straight suppression ratio, triple transit signals that are immeasurable, long-life operation without calibration, and high work reliability.
