Set defence means

Abstract

A defence system for a land area, intended as an alternative to land mines. The system includes sensors for detecting intrusions in the area, a weapon having multiple barrels and multiple projectiles ready for firing, and a controller that receives signals from the sensors to fire the weapon. The controller preferably requires intervention of an operator in order to trigger the weapon. The weapon may contain a range of projectiles for different purposes.

Description

[0001] 1. Field of the Invention[0002] This invention relates to defence means. In particular this invention relates to set defence means for defending a designated area.[0003] 2. Discussion of the Background Art[0004] Conventional set defence means for defending a designated area is by placement of concealed land mines throughout the designated area. These land mines are normally placed randomly throughout the designated area.[0005] This form of set defence has been widely used in the past and unfortunately it has resulted in many past war zones remaining mined long after peace has returned to the zone. This often renders good fertile land unusable and causes widespread injury to innocent civilians.[0006] Furthermore areas which are mined are not normally mined with a view to preventing all personnel passing beyond the mined zone. Typically areas are mined so that the likelihood of personnel being injured is high. This acts as an effective deterrent to ingress upon the mined zone. ...

AI Technical Summary

Benefits of technology

[0018] This preferred arrangement provides the advantage of the set defence means being relatively transportable and compact and thus easily concealed while providing the ability to deliver relatively large numbers of projectiles to the detected zone in a very short space of time.

[0019] The set defence means can also be of a one-use disposable type enabling size optimization to be more easily achieved and also providing cost benefits. This has benefits over conventional weapons in that each set defence module is free of ammunition feed and ejection systems, breech opening or mechanical operation. This enables each defence module to be self-contained in a compact shell or container which may be partially buried readily deployed without much concern.

Problems solved by technology

This form of set defence has been widely used in the past and unfortunately it has resulted in many past war zones remaining mined long after peace has returned to the zone.

This often renders good fertile land unusable and causes widespread injury to innocent civilians.

Typically areas are mined so that the likelihood of personnel being injured is high.

Likewise, mines may be cleared from a relatively narrow path through the mine zone in order to render the mining ineffective for preventing an enemy breaching the mined zone.

Unfortunately the random placement of the mines make them difficult if not impossible to recover at a later date.
