Product Description
The LK-DS-HES series of radio altimeter simulators represents a specialized class of photoelectric delay systems, meticulously crafted to cater to the intricate demands of radio altimeter simulator development, calibration, and maintenance. These systems are underpinned by the sophisticated technology of fiber-optic delay lines, which utilize optical fibers as the transmission medium and capitalize on the phenomenon of light delay to accurately replicate the spatial propagation of RF microwave signals. This innovative approach allows for the emulation and precise quantification of signal transmission at diverse altitudes.
In contrast to the traditional Surface Acoustic Wave (SAW) delay line systems, the LK-DS-HES series exhibits a suite of enhanced capabilities:
Broad Frequency Bandwidth;Superior Directivity Suppression;Advanced Triple Transit Signal Management:;Extended Service Life Without Recalibration;Optimized Work Reliability;
These advanced features position the LK-DS-HES series as a premier choice for radio altimeter simulator applications, surpassing the performance and reliability of conventional SAW delay line systems.
