Abstract

A radar test set target which is co-located with the radar and produces a faithful replica of the radar signal substantially delayed in time. The radar signal modulates a laser light which is controllable delayed in time by transmitting the modulated laser light through a fiber optic delay line. The output of the delay line is demodulated and the extracted and delayed radar signal is returned to the radar as a test signal.
