Abstract: 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.

Abstract: An inertial measurement unit (IMU) includes an inertial sensor assembly including a plurality of accelerometers and a plurality of rate gyroscopes, an inertial sensor compensation and correction module, and a Kalman estimator module. The inertial sensor compensation and correction module is configured to apply a set of error compensation values to sensed acceleration and rotational rate to produce a compensated acceleration and a compensated rotational rate of the IMU. The Kalman estimator module is configured to determine a set of error correction values based on a difference between a change in integrated acceleration of the IMU and a change in true airspeed of the IMU. The inertial sensor compensation and correction module is further configured to apply the set of error correction values to each of the compensated acceleration and the compensated rotational rate to output an error-corrected acceleration and an error-corrected rotation rate.

Abstract: A dual-mode laser-based and image-based seeker for projectiles, missiles, and other ordnance that persecute targets by detecting and tracking energy scattered from targets. The disclosed embodiments use a single digital imager having a single focal plane array (FPA) sensor to sense data in both the image-based and laser-based modes of operation. A control mechanism controls pixel scanning at a sub-window of the FPA to tightly control the imager's shuttering to detect, decode and localize in the imager's field-of-view a known pulse repetition frequency (PRF) from a known designator in the presence of ambient light and other confusing target designators, each having a different PRF.

Abstract: A system to merge and exploit two uniquely different types of seeker homing modes of functionality into a single, dual-mode seeker, using only an FPA as the active sensor to achieve both modes of operation. The disclosed embodiments also provide a means to actively designate & track, and also passively track the same target between active designation pulses to track a target at an update rate higher than the designator pulse rate with less demanding automatic target tracking algorithms. The disclosed embodiments eliminate the need for automatic target acquisition/recognition algorithms necessary for purely passive target tracking. The passive tracking methodology “aids” the passive tracking algorithm, based on frame-to-frame image registration, with active SAL track information to improve overall seeker guided weapon performance.
