ABSTRACT:
A device for electromagnetically encoding an energy passive munition prior o launch. A high frequency (HF) external energy source charges a first rectifier-capacitance circuit, having a relatively long time constant, via a secondary receiving coil. The first rectifier-capacitance circuit acts as a temporary power source for energizing programming circuitry capable of receiving subsequently pulsed HF encoding signals. A second rectifier-capacitor circuit, having a shorter time constant, is used to energize logic circuitry for programming a nonvolatile memory in binary coded bits. The binary code information is used to set a timer which subsequently causes the munition to self-destruct after launch in a time period in accordance with encoded signals stored in a memory.
