Application No. 10/126,569
BACKGROUND
The invention relates to repetitive waveform generators that can be employed in
radio frequency (RF) applications such as radar. Representative claims 1 and 12 are
reproduced below.
1. A repetitive waveform generator comprising:
a circuit for generating an optical signal having a predetermined duration;
a first optical coupler responsive to said optical signal and an optical
feedback signal;
an optical delay circuit responsive to said first optical coupler and
providing a delayed version of said first coupler output as an optical delay circuit
output; and
a second coupler responsive to said optical delay circuit output for
providing a waveform generator output, and for providing a portion of said optical
delay circuit output as said optical feedback signal to said first coupler;
wherein said first coupler provides said feedback signal to said optical
delay circuit; and
whereby said waveform generator output comprises a replica of said input
optical signal and a series of copies of said replica.
12. A repetitive waveform generator comprising:
a circuit for generating an optical signal having a predetermined duration;
and
means for recirculating said optical signal to generate repetitions of said
optical signal.
