  • Patent number: 4560120
    Abstract: SSICM is a missile configuration which employs spin stabilization, nutatil motion, and impulsive thrusting, and a body mounted passive or semiactive sensor to achieve very small miss distances against a high speed moving target. SSICM does not contain an autopilot, control surfaces, a control actuation system, nor sensor stabilization gimbals. SSICM spins at a rate sufficient to provide frequency separation between body motions and inertial target motion. Its impulsive thrusters provide near instantaneous changes in lateral velocity whereas conventional missiles require a significant time delay to achieve lateral acceleration.
