Coherent radar using recirculating delay line |
摘要 |
A portion of a radar transmit pulse is inserted into a recirculating delay line having a one cycle delay equal to the duration of a transmit pulse. A pulse train coupled from the recirculating delay serves as a local oscillator for the radar receiver. The delay medium may be an optical fiber, a coaxial transmission line or a surface acoustic wave (SAW) device.
