Hello Gautam,
Conducting a feasibility study on using optical fibers for RF transmission in fighter aircraft involves both simulation and practical experimentation. This can be a complex task, but here's a general guide to help you get started:Instruments and Equipment
- Optical Fiber Components:
- Optical Fibers: Single-mode or multi-mode fibers depending on the application.
- Optical Transmitters and Receivers: To convert RF signals to optical signals and vice versa.
- Optical Modulators: Mach-Zehnder modulators are commonly used for RF over fiber.
2. RF Equipment:
- Signal Generators: To generate RF signals at the desired frequencies.
- Spectrum Analyzers: To analyze the RF signals before and after transmission.
- Antennas: Suitable for the frequency range you are studying.
3. Optical Equipment:
- Optical Spectrum Analyzers: To analyze the optical signals.
- Optical Power Meters: To measure optical power levels.
4. General Lab Equipment:
- Oscilloscopes: For time-domain analysis.
- Network Analyzers: For measuring S-parameters and other RF characteristics.
Procedure
- System Design:
- Define the frequency range and system requirements.
- Design the RF over fiber link considering factors like link budget, bandwidth, and signal integrity.
2. Simulation:
- Use simulation software like MATLAB, OptiSystem, or VPIphotonics to model the RF over fiber system.
- Simulate the modulation, transmission, and demodulation processes.
3. Experimentation:
- Set up the optical fiber link with the necessary components.
- Transmit RF signals through the optical fiber and measure the output.
- Compare the transmitted and received signals to evaluate performance.
I hope it helps!
