The LEE capable of emulating the echoes of a spatial lidar at three wavelengths (355 nm, 532 nm, and 1064 nm) was developed. In general, it enables the characterization of the critical optical parameters of the detection chain of a space or airborne lidar. The LEE allows short overlapping echo with long echo with 63 dB dynamic range. In-depth characterization of the lidar detection module will evaluate compliance with the requirements for which it was designed and feed future designs with actual figures from the lidar detection chain.

The LIDAR Echo Emulator (LEE) emulates the returned signals from a Lidar system. As the return signal of a Lidar system depends on the target, this implies the capability of shaping the laser’s returns. In brief, a long echo corresponds to a natural or diffusive object (canopy, clouds) and short echoes to a complex thing like roofs, ground, etc. Such signals must be simulated to study and validate new detectors and detection systems without developing/procuring the entire Lidar system.

Switching DC-DCs regulate the output voltage based on energy flow into and from the DC-DC by controlling the duty cycle of the on and off states. When the switch is conducting, energy flows from the input source into the converter and in the case of a buck, some of this gets stored in the inductor as magnetic energy (0.5*LI2) while some gets delivered directly to the output (forward topology).
