VISUAL DISRUPTION SYSTEM, METHOD, AND COMPUTER PROGRAM PRODUCT

摘要

Aspects of the disclosed subject matter involve airborne-based systems, methods, and computer program products for optimizing a laser-based visual disruption countermeasure scan pattern. The scan pattern can be comprised of a plurality of lasers each with their own scan pattern and may be used to disrupt an optical system of a weapon or an individual. Based on the scan patterns and/or data used to generate the scan patterns, the shape or intensity of the scan pattern or patterns can be modified.

主权项

1. A laser-based visual disruption countermeasure system on-board a helicopter, the system comprising:
a hostile fire indicator subsystem on-board the helicopter to identify locations of stationary or moving ground-based threats to the helicopter and to generate respective ground-projection zones around the identified locations indicative of possible error in the identified locations, each of the zones around the identified threat locations being in the form of an ellipse; and an eye-safe laser-based visual disruption subsystem on-board the helicopter to generate and output a plurality of laser beams with intensities sufficient to interfere with and temporarily impair a human optical system, each laser beam being output so as to follow a rectangular scan pattern completely enveloping a corresponding ellipse defining the zone indicating possible error in a corresponding identified threat location, irrespective of current position of the helicopter, said eye-safe laser-based visual disruption subsystem being operative to maintain at the same time two or more of the rectangular scan patterns, wherein the system is configured and operative to determine whether any of the two or more rectangular scan patterns maintained at the same time overlap, and to increase applied laser beam energy only for any overlapping portion.
