Abstract
The present application relates to radio detection and ranging (radar) systems and, in particular, to a radar system having a photonics-based signal generator. Such a radar system comprises a stepped-frequency optical signal generator, an optical-to-electrical converter, and a transmitter. The stepped-frequency optical signal generator is configured for converting an optical signal into a stepped-frequency optical signal. The optical-to-electrical converter for converting the stepped-frequency optical signal into a stepped-frequency electrical signal. The transmitter for transmitting a microwave signal based on the stepped-frequency electrical signal.
Claims18
A radar system comprising:
- a stepped-frequency optical signal generator configured for converting a first optical signal into a stepped-frequency optical signal;
- a second light source configured for transmitting a second optical signal;
- an X-junction optical beam splitting device configured for receiving the stepped-frequency optical signal and the second optical signal and for combining the received signals into a reference signal;
- an optical-to-electrical converter for converting the reference signal into a stepped-frequency electrical signal;
- and
- a transmitter for transmitting a microwave signal based on the stepped-frequency electrical signal.
