RADIO ALTIMETER TEST SET

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.

 

Features of Radio Altimeter Simulator

  • Wide simulated height range(0 to 22000 above );
  • High simulate altimeter accuracy(≥1‰);
  • Optional simulate configuration(support more than 210 configurations);
  • Manual switch and automatic switch;
  • Volume miniaturization, strong electromagnetic compatibility, high work reliability;
  • Multiple control mode: UART, LAN, etc. ;
  • Various standard tests platform interface such as PXI, VXI, LXI.

Application of Radio Altimeter Simulator

  • Place: Radio altimeter for radar,AEW,satellite,helicopter and etc
  • Measure the accuracy of the altimeter
  • Measure the sensitivity of research and tracking
  • Measurement of another parameter

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.
