· Variable reluctance sensors are passive sensors as they don’t require external power supply
· Target material must be ferrous only.

LIDARs use the standard pulsed time of flight measurement technique using a micro-controller

that processes the measured data to estimate theposition and speed of the target. Velocity estimates are made using a tracking filter or by measuring the change in range as determined by the varying time of flight between successive pulses.
