Abstract:
1. A system for determining the distance between a target and a laser guided weapon traveling towards the target comprising: a laser designator on a remote platform for radiating a first train of pulses on a set wavelength in the direction of the target; a receiver in the weapon to receive and detect pulses on the set wavelength reflected from the target; a direction sensing means in the weapon for determining the direction of the target; a transmitter in the weapon to periodically transmit a second train of pulses on the set wavelength in the direction of the target; means in the receiver to extract a reflection from the target of the second train of pulses; timing means to determine the period of time from transmitting the second train of pulses to receiving the reflection from the target of the second train of pulses; and computing means for determining a distance corresponding to said period of time.
