Abstract
A satellite defends itself by having a plurality of corner cube retroreflectors with shutters, each having a laser light sensor. It is assumed that the attacker first must obtain positional and range information with a pulsed laser. When one of the sensors detects these low power laser pulses, it causes the shutter of the corner cube array to open and return the pulses with sufficient strength to saturate or damage the attack sensors.
