Laser radar proximity igniter with mask discrimination for ordnance ignition has ignition pulse to be triggered by laser distance measurement device triggered on falling edge of received echo pulse profile

摘要

The device has a laser distance measurement arrangement and mask discrimination. The ignition pulse to be triggered by the laser distance measurement device is triggered on the falling edge of the received echo pulse profile. The ignition pulse is triggered when the difference of the non-delayed echo pulse profile and the delayed damped echo pulse profile changes sign.
