Sight

An apparatus for providing information for adjusting a sight of a projectile weapon, the apparatus comprising at least one processor and at least one memory, said at least one memory comprising computer code when executed by at least one of the at least one processor causes the apparatus to:

• receive information of frequency or wavelength of a signal transmitted toward a projectile in flight, which projectile has been fired from a projectile weapon;
• receive information of frequency or wavelength of a signal reflected from the projectile in flight;
• determine a difference of frequency or wavelength between the transmitted signal and the received signal;
• use the difference of frequency or wavelength to determine a velocity and acceleration of the projectile;
• model a flight path of the projectile based on the determined velocity and acceleration of the projectile;
• determine adjustment information for adjusting the sight of the projectile weapon based on the modelled flight path and a current angle difference between a barrel axis of the projectile weapon and the sight.

A non-transitory computer-readable medium storing a program for providing information for adjusting a sight of a projectile weapon including instructions that, when executed by at least one processor causes an apparatus to:

• receive information of frequency or wavelength of a signal transmitted toward a projectile in flight, which projectile has been fired from a projectile weapon;
• receive information of frequency or wavelength of a signal reflected from the projectile in flight;
• determine a difference of frequency or wavelength between the transmitted signal and the received signal;
• use the difference of frequency or wavelength to determine a velocity and acceleration of the projectile;
• model a flight path of the projectile based on the determined velocity and acceleration of the projectile;
• determine adjustment information for adjusting the sight of the projectile weapon based on the modelled flight path and a current angle difference between a barrel axis of the projectile weapon and the sight.

A method for adjusting a sight of a projectile weapon, the method comprising:

• receiving information of frequency or wavelength of a signal transmitted toward a projectile in flight, which projectile has been fired from a projectile weapon;
• receiving information of frequency or wavelength of a signal reflected from the projectile in flight;
• determining a difference of frequency or wavelength between the transmitted signal and the received signal;
• using the difference of frequency or wavelength to determine a velocity and acceleration of the projectile;
• modelling a flight path of the projectile based on the determined velocity and acceleration of the projectile;
• determining adjustment information for adjusting the sight of the projectile weapon based on the modelled flight path and a current angle difference between a barrel axis of the projectile weapon and the sight.
