<p>PURPOSE:To eliminate operation except at a target by providing a second discriminator for deciding to output a high level when a distance value indicated by a distance signal becomes a predetermined value or less, and an ignition driver for operating an ignition when both the outputs of first and second discriminators become high levels. CONSTITUTION:A distance signal A to be supplied from a guiding device placed in a missile is input to a discriminator 4b. When the missile approaches a target and the signal A indicates a value for a predetermined distance, the discriminator 4b outputs a high level to an AND gate of a driver 4. Both discriminators 4a, 4b output high levels and a 2-input AND gate of a driver 5 satisfies an AND condition, the driver 5 outputs a drive signal to an ignition circuit 6 based on the output of the gate to ignite powder. The amplitude of a reception signal level for sending a high level output and distance of the discriminators 4a, 4b are previously set based on performance of the missile. An operation except at a target can be remarkably suppressed.</p> |
