摘要:
A beam director subsystem (12) and method for use in a weapons system. The beam director subsystem includes a source (20) of electromagnetic radiation for generating a high energy laser (HEL) beam (18). The electromagnetic radiation is directed to a secondary mirror (22) that reflects the electromagnetic radiation to a primary mirror (24) for output of the HEL beam. The secondary mirror is generally curved and expands the electromagnetic radiation received from the source prior to outputting the HEL beam from the primary mirror. The subsystem further includes a track telescope (28) coupled to the housing. The track telescope has a track detector (30) configured to receive electromagnetic radiation originating from the HEL and electromagnetic radiation emitted from an illuminator (32) and reflected from an airborne target.

摘要:
A method and system for aligning a tracking beam and a high energy laser (HEL) beam (18) includes a tracking beam and a HEL beam. A detector (30) receives at least a portion of the tracking beam, wherein the tracking beam received at the detector has been reflected from the airborne target. The detector also receives a first portion and a second portion of the HEL beam prior to output through a housing (26). A processor (34) processes the signals to determine a relationship between the tracking beam and the HEL beam; and generates a control signal to steer the HEL beam to the airborne target based upon the determined relationship.
摘要:
A discrete state-space filter directly applies a linear transfer function that describes the frequency -domain representation of an IIR filter or control plant to asynchronously sampled data. The discrete state-space technique maps a continuous lime transfer function into the discrete state-space filter and stores the states of the filter in a sample-time independent fashion in a discrete state-space vector (step 18). The filter states are propagated with the asynchronous time measurements provided with the input data to generate the filtered output (steps 20 and 22)
