Target Separation from Sabot with Permanent Magnetic Array and Beam Steering Method with Four-Wave Mixing

Abstract

We developed the permanent magnet array to separate a target from a sabot and analyzed the deceleration of the sabot velocity per unit length. The injection accuracy is about ± 12 mm at one meter from the injector muzzle when the sabot velocity is around 30 m/s. The method of compensation of a phase conjugate beam with four-wave mixing is shown. As one pump beam for four-wave mixing has a bit of longitudinal angle from the plane that another pump beam and a seed beam propagate, the phase conjugate beam tilts at the same angle from the plane. The displacement angle of the phase conjugate beam is compensated by adequately adjusting the angle between two pump beams.
