RF data communications link for setting electronic fuzes

Abstract

Fuze setting data for setting a projectile fuze may be transferred from a fuze setter to a fuze over a radiative data link. The radiative data link may comprise a signal transmission over one or more bands selected from a group consisting of the audio, ultrasonic, infrared, RF, visible and UV bands of the electromagnetic spectrum. In one embodiment, frequency shift keying is used to modulate a radio frequency carrier signal. Operational power for the fuze may be inductively transferred from the fuze setter to the fuze over a magnetic inductive link.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates generally to a communications link between a fuze setter and a fuze, and more specifically to an improved fuze setter capable of transmitting a magnetic inductive power carrier signal and a separate high speed data signal. [0002] Multifunctional electronic fuzes for artillery and other projectiles are generally known in the art. For example, U.S. Pat. No. 5,497,704 teaches a multifunctional magnetic fuze, the entire disclosure of which is incorporated herein by reference. Multifunctional electronic fuzes may be programmed to trigger detonation of a projectile upon the satisfaction of various parameters, such as time-to-burst, turns-to-burst, height of burst, proximity, and the like. [0003] Fuzes may be programmed by a fuze setter before the projectile is launched. Generally, fuzes are powered up and set or programmed using a magnetic inductive link between the fuze and the fuze setter. U.S. Pat. No. 5,497,704 and U.S. Pat. No...
