| 摘要 | A rocket ignition system (32) adapted for use with a missile (30) having a rocket motor (24). The system (32) includes detectors (34, 36) and circuitry (22, 34, 36, 38, 40) for detecting an optical impulse and a pressure wave, both of them being components of a launch signal. In the illustrative embodiment, the system (30) includes a primer for generating the launch signal having. A processor (38, 40) computes the difference between the time elapsed between the receipt of both of the signal components and provides an ignition signal to the pyrotechnic rocket motor igniter (22) if the difference is within a predetermined valid time range. The predetermined valid time difference is computed based on the difference in position between both if the detectors, and the difference in velocities of said signal components. A safety switch (48) blocks the ignition signal when the missile (30) is not ready for use. | ||||||
