Abstract:
1. A method of testing a detection and ranging system, the method comprising: receiving an input signal from a detection and ranging system, triggering a light source to output a pulse; transmitting the pulse into a first end of a plurality of fiber optical delay lines for passage through a length of each fiber optical delay line of the plurality of fiber optical delay lines; and transmitting the pulse out through a second end of each fiber optical delay line of the plurality of fiber optical delay lines, wherein each second end of the plurality of fiber optical delay lines is arranged within a target plane, the pulse output yielding return signal transmissions from the target plane to the detection and ranging system and ranges generated at two or more locations, wherein each of the return signal transmissions is delayed by at least a time for the pulse to traverse the length of the respective fiber optical delay line.
