Introduction of Radio Altimeter Simulator

DS-HES series radio altimeter simulators are photoelectric delay systems specially developed for various radio altimeter simulators’ production, measurements, and maintenance. 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.

NEON’s radio altimeter test set mainly contains three models: standard case, portable and core module.

Working Principle of Radio Altimeter Simulator

Radio Altimeter Simulator is mainly composed of an RF attenuation module, electrical/optical conversion module, optical fiber delay module, optical/electrical conversion module, RF amplification module, adjustable attenuation module, power supply conversion module, microcomputer control, and touch display module. It is used to complete the altitude excitation of the radio altimeter in the laboratory environment.


Advantages of Radio Altimeter Simulator

Compare with the traditional SAM(surface acoustic wave) delay line system, the DS-HES series radio altimeter simulator 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.
