Product Description
The LK-DS-HES series radio altimeter simulators are sophisticated optoelectronic delay systems meticulously engineered for the specific needs of radio altimeter simulator production, measurement, and maintenance. These systems are predicated on the advanced fiber-optic delay line technology, harnessing the properties of optical fiber as the transmission medium and leveraging the inherent light delay to emulate the spatial propagation characteristics of RF microwave signals. This technological approach enables the simulation and precise measurement of transmissions at varying altitudes, providing a versatile tool for a range of applications.
Distinct from conventional Surface Acoustic Wave (SAW) delay line systems, the DS-HES series is characterized by a number of superior attributes: Extended Frequency Bandwidth；Enhanced Directivity Suppression； Management of Triple Transit Signals；Sustained Operation Without Calibration；Elevated Operational Reliability.
These distinguishing features establish the LK-DS-HES series as a cutting-edge solution for advanced radio altimeter simulator applications, offering improved performance and dependability compared to traditional SAW delay line systems.
