Such data may be used to update target or trajectory information used by a projectile. Transmission of such data, at high data rates, just prior to firing the projectile from the gun tube, enhances the probabiity of target kill or damage. High data rates, compatible with SMART projectile requirements, are made possible by ultrasonic signal frequencies in the range of about 500 Khz to about 2,500 Khz. Phase-shift-keyed modulation may be employed to impart data onto the ultrasonic signals. | |
