In defense applications, RFoF technology plays a critical role in comprehensive remote sensing, secure communication and surveillance systems. Such systems can be hardened against external interference preventing damage to sensitive sheltered equipment from electromagnetic pulse scenarios. RFOptic has a long track record of supplying governmental institutes and defense system integrators with advanced technologies for a wide variety of defense and homeland security applications.
We provide Optical Delay Line (ODL) and Altimeter for radar systems where radar range calibration is required, broadband systems for Electronic Warfare (EW). We also provide mmWave Satcom applications where our RFoF HSFDR links and subsystems above 40GHz are required as well as phase-matched system for electronic warfare applications.
FAQs
What RF over fiber (RFoF) solutions does RFOptic offer for electronic warfare (EW) applications?
RFOptic offers several RFoF solutions, including phase-matched WDM RF over Fiber (RFoF) multi-link systems and optical delay lines suitable for EW test, training, and simulation environments.
Why is the Doppler shift in EW important, and does RFOptic's OFL support it?
The Doppler effect is a shift in signal frequency caused by relative motion between a transmitter (TX) and a receiver (Rx). It is critical for target velocity determination, moving target indication (MTI), and discriminating genuine threats from clutter or electronic counter-measures. RFOptic’s high-frequency Altimeter Optical Delay Line (ALT ODL) provides a high-performance solution for testing and calibration of radar altimeter systems, including simulation with Doppler modulation that simulates target movement. Standard optical delay lines can also be aded.
Why do EW and radar test labs prefer RF over fiber to coaxial cable?
Coaxial cables degrade high-frequency signals (such as X-band, Ku-band, and Ka-band) rapidly over short distances. RF over Fiber on the other hand, eliminates signal attenuation and high-frequency loss over long distances, which is crucial for signal fidelity in EW testing.
Is RFOptic a supplier of RF-over-fiber links for electronic warfare testing?
Yes, RFOptic is a leading supplier of RFoF for EW test solutions for defense EW and radar simulation labs that are currently deployed at global defense companies wordwide. Solutions include Optical Delay Line (ODL) and Altimeter for radar systems where radar range calibration is required, and broadband systems for Electronic Warfare (EW). For mmWave Satcom applications, RFOptic is a vendor of RFoF High SFDR links and subsystems, also above 40GHz, and phase-matched systems for EW applications.
What technology is used to test radar systems without long RF cable runs?
Optical delay lines (ODLs), which can also be progressive) are commonly used to replace long RF cable runs in radar testing. Optical Delay Lines (ODLs) use fiber optics to delay the radar signal for a set time and bounce it back as a simulated target without high signal loss. This replaces the need for bulky copper coaxial cables that cause massive signal attenuation and distortion.
