Abstract
This is an electronics system that calculates and indicates the location from where small arms weapons are fired. The location of the shooter is calculated and then indicated via a directional finder device such a laser pointer type of indicator mounted on a rotating bed with tilt adjustment, or a third party device (such as a GPS). The location of the shooter may also be fed to an automated gun turret, which would be programmed to return fire at the location of the shooter and about the area of that person. The automated response to return fire can first be manually acknowledged with a sight camera fitted to the turret gun.
Description
I Title
Electronics system that calculates and indicates the location from where small anna weapons are fired.
Baekgrsund This invention relates so a siIem that is able to detect the location where a weapon system has been fired hum and provides a means so indicate that location. This system is to be used pnmanly for military and security purposes.
A fictitious scenario used as an example to explain die use of she system is: A military unit on patrol in a populated area 250 meters from the nearest building.
comes under small arms fire. A unit vehicle Isis taken a hit and the unit members stop and sly to locate the person firing the weapon. They would normally do this by physically looking to find the location of the shooter before returning flre The unit members may or may not locate the shooter before they move or fire another shot.
This places the unit in a posit on where they may be exposed to the shooter and in the direct line of fire as they arc not aware of shooter's position.
Statement of invention
With this system in place, she location of the shooter would have been calculated within a short period of time (it Is possible to do so within I second). The location could be indicated via a directional finder device such a laser pointer type of indicator mosmtai on a rotating bed with dli adjustment, or a third party device (such as a GPS). In addition, the location of the shooter could be fed so an automated gun turret, which would be programmed to return fire at the location of she shooter and about the area of that person. The automated response to return fire can first be manually acknowledged with a sight camera fitted to the turret gun.
Advantages * Thcshoo(ercouldbeshotatwithinafewsccondsofflringthefuStsingle bullet * An enemy couldn't fire at the unit without giving away its position.
* A sniper's location would not remain unknown if they lire a shot, no matter how good their concealment was.
* II a tracer round was fired from the automated turret gun, it would provide a direct position reference that any members of the unit could fire upon.
* Directional control can be set so that the system can cover a specified area.
* When set to a folly automatic mode, the system can deal with multiple targets, computing all incoming fire while controlling the automated turret gun and firing upon all targets in sequence.
* The threat to persons being fired upon directly after the first single bullet was fired would be eliminated, therefore no more bullets would be fired from the sense source.
Introduction to drawings
An example of the invention will now be described by refening to the accompanying drawings: Figure 1 shows a blocI diagram of the system.
Detailed description
The system uses a three axis magnetic field sensor and comprises an input interface, a processor unit and output interfacs Referring to Figure), wiuich shows a block diagram of the system, the input Interface to which the sensor connects consists of an anti.aliasing filler stage and an Analogue to Digital converter stage There are one of eachof these stages for each of the three input channels. There is one input channel for one axis of magnetic field measurement. There sit also some push button switches, which arc used for some basic configuration type commands. The processor stage consists of a microprocessor with external memory, both random access memory (RAM) and programmable read only memory (ROM). There are also some switches and an liquid crystal display (LCD) connected to the processor. This user intcrfecc is used to place the system into a particular mode for configuration, and to also display resultant vector and distance values The processor takes data from the A/D converters and processes it using an algorithm, and then passes data to the output stage as well as to the system LCD. The output interface is used to connect to directional pointers and gun turrets or any third party requirement for data representation. Connection to third party devices is possible by updating the software algorithm.
The system analyses the change in magnetic field measured by the three axis magnetic field sensor. The change in magnetic field takes place when a projectile such as a bullet or mortar passes in range of the sensor. The processor calculates the directional vector and distance of die origin of the projectile to widiina small error percentage. This information can be then passed on to location systems such as GPS or laser pointer and also to targeting systems for automated weapons.
As the algorithm is software based, it may be upgraded at any point in time.
The system can run in various modes depending on a particular situation. These mode can be changed by selecting from a menu on the graphical user Interface.
The system has a power switch and Is able to run from a single power supply, such as a car or muck battery supply, a portable battery or power source and mains power.
