    Abstract: An underwater supercavitating projectile includes means to form ripples on its surrounding cavity so as to provide well-defined disturbances of the cavity boundary. As the ripples move aft of the supercavitating projectile and into the wake behind the advancing projectile, the ripples detach to form a pattern of vapor bubbles in the wake that are distinct in both size and regularity from the typical vapor bubbles formed as the cavity collapses behind the advecting projectile. Sensors record the track of the projectile along its path based on the distinct acoustic signature of the vapor bubbles. Combined with the acoustic echo from a target, the relative distance of the projectile to the target can be determined using methods known in the art. Multiple projectile trajectories are used to increase the ability to resolve the target by adjusting the aiming of the projectiles to reduce the relative distance.

    Abstract: The method of mounting a radar reflector on an artillery shell contemplates providing a body constituted by a functional element and a sleeve element formed rotationally-symmetrical about a lengthwise axis of said body with at least one explosive device arranged at least at the neighborhood of an outer surface of said sleeve element near to one end of said sleeve element and remote from the functional element. The body is mounted on the artillery shell and the explosive device is detonated in order to establish a form-locking connection of the sleeve element with the shell. The detonation of the explosive device severs the sleeve element at the region of said one end of said sleeve element in order to provide a substantially straight-lined closure of the sleeve element about the artillery shell in order to avoid undesirably altering ballistic characteristics of the artillery shell.

    Abstract: A projectile, that can be tracked by optical means, is fitted with a special tracer incorporated into the projectile's trailing edge. The rearward facing special tracer is incorporated into a metal disk which is crimped to the projectile's metal jacket. The special tracer includes micro-prismatic features that reflect light at the incidence angle. Alternatively, the disk incorporates a fluorescent dye that is responsive to a laser emission. External emitted radiation is reflected or re-emitted from the trailing edge of the projectile, allowing for an external electro-optic tracking device to identify the position of the projectile in flight.

    Abstract: A low observable photoluminescent tracer projectile, for use with a small caliber weapon at night—which utilizes a base phosphor material of Ca, Sr and S, or a base phosphor material of Y2, O2, and S—with a combination of minor dopant ingredients; which base phosphor material is mixed with a clear binder to form a photoluminescent material which is applied to the rear end, or base, of a small arms projectile as a thin layer; to which thin layer is added a layer of small retro-reflectors—whereby, when this projectile is fired from the weapon, the photoluminescent mixture will be activated and will be observable, using night vision at an angle of 0 to about 20 degrees from the rear end of the projectile.

    Abstract: A system for correcting the aim of a weapon which is operative to launch a projectile from a barrel on a ballistic path toward a target. A rear surface of the projectile is coated with a fluorescent dye that re-emits radiation when excited by laser radiation. The system includes a source of laser radiation (strobe) pulses that form a cone of light intersecting the ballistic path of the projectile. The strobe pulses are emitted at predetermined times (T1, T2, T3, . . . Tn) following firing of the projectile (at time T0). An optical detector receives the radiation re-emitted by a the fluorescent dye at the rear of the projectile at times (T1z, T2z, T3z, . . . Tnz) producing measurable location signals allowing the system to measure the vertical and lateral positions of the projectile at said times, where “z” is a re-emission delay and T1z, T2z, T3z, . . . Tnz are the respective times T1, T2 , T3, . . . Tn each delayed by amount z.

    Abstract: A high velocity acoustic signal producing underwater shotgun system for dispersing a plurality of relatively small supercavitating projectiles over a wide spatial field at long range using the dynamics of cavity collapse for better target localization in underwater mine clearance. A typical supercavitating projectile design is enhanced to produce a two-staged projectile in order to accomplish this innovation. The first stage of the two stage design allows for the long range firing underwater typical of a supercavitating projectile while the second stage permits the coverage of a wide area with a plurality of small supercavitating projectiles just as the first stage projectile reaches its fixed range. A distinctive feature of the radiated noise from a supercavitating projectile contacting a solid object is used in conjunction with the two stage projectile design to provide a system for underwater mine clearance verification. The distinctive noise signal may also be used in conjunction with an underwater targeting system to help identify, localize and track targets as well.
