Purpose of the Study:
- To conceive and demonstrate a flexible photonic radar warning receiver.
- To achieve reconfigurable broadband and narrow-band operation within a single system.
Main Methods:
- Development of a photonic radar warning receiver architecture.
- Implementation of a cascaded grating for wavelength-dependent time delays.
- Demonstration of system reconfiguration for different operational modes.
Main Results:
- Successful conception and practical demonstration of the photonic radar warning receiver.
- The system exhibited high flexibility in frequency measurement range and resolution.
- Achieved reconfigurable operation between broadband, low-resolution and narrow-band, high-resolution modes.
Conclusions:
- The cascaded grating approach effectively enables adaptable frequency measurement in photonic radar systems.
- The demonstrated system offers a flexible and reconfigurable solution for radar warning receiver applications.
