Method and device for tracking a moving target object

1. A method for tracking a moving target object, comprising the steps:

a) identifying the target object;

b) marking the target object with a marking invisible in a visible spectrum but retro-reflective in a selected wavelength range of invisible spectrum of light;

c) tracking the marked moving target object with an image capture device provided on an aircraft carrying a rocket, wherein the image capture device is sensitive in the selected wavelength range of the invisible spectrum;

d) deploying the rocket towards the marked moving target object, wherein

the marking is formed by an invisible marking paint that is retro-reflective in the selected invisible wavelength range, the marking paint has a paint and retro-reflective particles embodied therein, wherein the particles in the selected wavelength range of the invisible spectrum of light have a refractive index sufficient for a retro-reflection,

the paint and the particles embedded therein are translucent in the visible spectrum of light,

the retro-reflective particles have a same refractive index as the paint in the visible spectrum of light, so that the marking paint is transparent in this spectrum,

the marking paint is applied to the target object from a distance, wherein the application of the marking paint is carried out by a paintball shooting device, and

the aircraft and the paintball shooting device are arranged in different locations.

2. The method according to claim 1 , wherein the selected wavelength range is in an infrared spectrum.

3. The method of claim 1 , wherein the aircraft is a helicopter or a wing aircraft.

4. The method according to claim 1 , wherein

the aircraft includes a position-determining device, and

a determination of a position data of the marked target object is performed based on a position determined using the position-determining device and an angle of view to the marked target object.

5. The method according to claim 1 , wherein the aircraft is positioned between a natural source of illumination and the marked target object.

6. The method of claim 5 , wherein the natural source of illumination is a sun or moon.

7. A method for tracking a moving target object, comprising the steps:

a) identifying the target object;

b) marking the target object using a marking paint that is shot from a paintball shooting device located at a distance from the target object, wherein the marking paint is invisible in a visible spectrum but retro-reflective in a selected wavelength range of invisible spectrum of light;

c) tracking the marked moving target object with an image capture device provided on an aircraft carrying a rocket, wherein the image capture device is sensitive in the selected wavelength range of the invisible spectrum; and

d) deploying the rocket towards the marked moving target object,

wherein the aircraft and the paintball shooting device are arranged in different locations.

8. The method according to claim 7 , wherein the marking paint includes paint and particles embedded in the paint, wherein the paint and particles have different refractive indices in the selected wavelength and the paint and particles have a same refractive index in the visible spectrum.

9. The method according to claim 7 , wherein the selected wavelength range is in an infrared spectrum.

10. The method of claim 7 , wherein the aircraft is a helicopter or a wing aircraft.

11. The method according to claim 7 , wherein

the aircraft includes a position-determining device, and

a determination of a position data of the marked target object is performed based on a position determined using the position-determining device and an angle of view to the marked target object.

12. The method according to claim 7 , wherein the tracking of the marked moving target is performed by the aircraft without emitting illumination by the aircraft.

13. A method for tracking a moving target object, comprising the steps:

a) identifying the target object;

b) marking the target object using a marking paint that is shot from a paintball shooting device located at a distance from the target object, wherein the marking paint is invisible in a visible spectrum but retro-reflective in a selected wavelength range of invisible spectrum of light;

c) tracking the marked moving target object with an image capture device provided on an aircraft, wherein the image capture device is sensitive in the selected wavelength range of the invisible spectrum; and

d) determining the position of the marked target object;

e) transmitting the position of the marked target object to a further aircraft carrying a rocket; and

f) deploying the rocket towards the marked moving target object, wherein the aircraft, the further aircraft and the paintball shooting device are arranged in different locations.
