Deployable, forward looking range sensor for command detonation

The system and method for accurately determining range-to-go for the time-delayed command detonation of a projectile. Using dual laser and/or radio frequency detectors on a spinning projectile to determine the range-to-go, time-to-go, or lateral offset from the projectile to the target. The detectors are forward facing and rear facing and are located in a tail kit such that cost can be greatly reduced on a spinning projectile. The deployable detector(s) may be a light pipe, mirrors, or the like and comprise APD or PIN diodes.

Method and apparatus for improving the aim of a weapon station, firing a point-detonating or an air-burst projectile

The method and apparatus for a remote weapon station or incorporated into manually-aimed weapons. The methodology requires use of a muzzle velocity sensor that refines the aiming of the second and subsequent fires or volleys fired from weapon systems. When firing the first volley a weapon uses an estimated velocity and, at firing, the muzzle velocity of a projectile is measured. When firing the second volley a weapon's fire control calculates an aiming point using the measured velocity of the first volley.

Projectile lens-less electro optical detector for time-to-go for command detonation

The system and method for accurately determining range-to-go for the command detonation of a projectile warhead. Using dual laser detectors on the tail and on the nose of a spinning projectile to determine the range-to-go, time-to-go, or lateral offset from the projectile to the target. The method for controlling a projectile warhead uses a large area PIN detector and an ogive window. If the PIN detector is large enough to capture the second laser signal, the window is no longer an optical element, only a window thereby drastically reducing the cost of the system. In some cases the detector on the nose of the projectile comprises several PIN diodes placed around the projectile as a distributed aperture. Distributed apertures may also be created by placing the PIN diodes on the wing roots or body of the projectile.

DIGITAL ACTIVE OPTICAL TARGET DETECTION SYSTEM
20190331795 · 2019-10-31 ·

Provided is a detection system that utilizes high dynamic range, monolithically arranged, digital pixel sensors for situational awareness, targeting, tracking or locating. The detection system transmits a radially outwardly directed set of laser pulses into an environment, aspects of the pulses being reflected back by environmental elements to a single pixel array. The single pixel array scans volumetric space proximate the environment for profile characterization of the reflected aspects by the detection system in terms of intensity and multiplicity. The detection system is configured to compare this profile against a library of profiles of known environmental elements to distinguish between the environmental elements and a target. The detection system may be disposed about an outer periphery of a projectile for use in determining when the projectile is proximate the target for triggering an actionable element of the projectile, such as an initiator fuze for an explosive system.

PROXIMITY FUSE HAVING AN E-FIELD SENSOR
20190331470 · 2019-10-31 ·

A proximity fuse includes an electric-field (E-field) sensor to detect electrical disturbances from an object that is external and distinct from a device carrying the proximity fuse. The E-field sensor detects or senses E-fields versus time in order to provide omnidirectional coverage of the device carrying the proximity fuse. When the device carrying the fuse is a missile having warhead, the proximity fuse is connected with detonation logic that detonates the warhead at a desired time to destroy or neutralize the object, which is typically a threat, such as another missile.

Phased array LIDAR in ordnance control

Apparatus and associated methods relate to controlling an explosive burst event of a ballistic ordnance, based on a ground surface topography mapped by a phased-array LIDAR system. The ground surface topography is mapped using an integrated photonics LIDAR system configured to: generate a beam of coherent light; non-mechanically steer a beam of coherent light over a solid angle about an ordnance axis; and detect the beam reflected from the ground surface. The integrated photonics LIDAR system is further configured to map the ground surface topography, based on a functional relation between an angle of the beam and a time difference between generating the beam and detecting the beam reflected from the ground surface. A timing and/or direction of the explosive burst can be controlled, based on the calculated ground surface topography, so as to advantageously realize a desired effect of the explosion.
