Definitions

  • the same apparatus may simply be used to more effectively engage a target, for example only engaging when engagement efficiency is at or above a threshold.
  • the target environment comprises the target, and may include all other areas which may be affected by the directed-energy weapon during engagement of the target (for example, due to energy reflected from the target).
  • the controller then controls the directed-energy weapon to direct energy towards the target environment conditionally upon the data or on the above-described parameters which depend on the data. This may include not engaging the target, or engaging the target, or engaging the target at a lower power, thereby avoiding or reducing collateral damage, as described below.
  • the same apparatus may simply be used to more effectively engage a target, for example only engaging when engagement efficiency is at or above a threshold.
  • the assessment comprises determining a possible engagement efficiency of the target by a directed-energy weapon; and the controller is arranged to, during an engaging phase, control the directed-energy weapon to direct energy towards the target environment conditionally upon the possible engagement efficiency.
  • the controller is arranged to, during the assessment phase, control the directed-energy weapon to use a main beam (i.e. a primary beam) to direct energy, and, during the engaging phase, control the directed-energy weapon to use the main beam to direct energy.
  • a main beam i.e. a primary beam
  • the main beam which may direct energy during the engaging phase
  • the controller is arranged to, during the assessment phase, control the directed-energy weapon to use a probing beam (i.e. a secondary beam) to direct energy, and, during the engaging phase, control the directed-energy weapon to use a main beam to direct energy.
  • a probing beam i.e. a secondary beam
  • control the directed-energy weapon to use a main beam to direct energy i.e. a secondary beam
  • a probing beam i.e. a secondary beam
  • the controller is arranged to, during the assessment phase, control the directed-energy weapon to use a main beam to direct energy.
  • a probing beam i.e. a secondary beam
  • control the directed-energy weapon to use a main beam to direct energy.
  • the probing beam may be coaxial (that is, share a same beam bath) as the main beam, at least in part, which might make it easier to calculate engagement based on the assessment (e.g. spatial offsets in main and probing beams may not need to be taken into account).
  • a speed and direction of travel of the target might also be used to factor in possible engagement efficiency at some future point in time.
  • the controller 16 controls the directed-energy weapon 18 to direct energy 34 towards the target environment 20 (more specifically, towards the target 22). This is illustrated by FIG. 6 .
  • the controller 16 controls the directed-energy weapon 18 not to direct energy towards the target environment 20. This may reduce the risk of collateral damage, or avoid engaging the target when such engagement will be neither satisfactory nor successful.
  • the controller 16 controls the directed energy weapon 18 to direct energy towards the target environment at a first power level, and, in response to the possible engagement efficiency being above the second predetermined level, the controller 16 controls the directed energy weapon 18 to direct energy towards the target environment 20 at a second power level, which is greater than the first power level. This helps to avoid collateral damage in situations in which the possible engagement efficiency is less than the second predetermined level, whilst allowing the directed-energy weapon 18 to engage the target.
  • the apparatus 12 comprises the directed-energy weapon 18, this is not always the case, and that the controller 16 may control a directed-energy weapon which is remote to the apparatus 12.
  • the controller controls the directed-energy weapon to use the main beam (which is also used during the engaging phase) to direct energy.
  • the vehicle may comprise a dedicated probing beam to be used during the assessment phase.
  • This probing beam may be lower power than the main beam and may be designed specifically for performing the assessment during the assessment phase. It will be appreciated that in either case, beam optics are provided to form the main and/or probing beams.
  • FIG. 1 might relate to an apparatus 12 for a directed-energy weapon 18, the apparatus 12 comprising an assessment system 14 arranged to perform an assessment of a target environment 20, wherein the target environment 20 comprises a target 22, and the assessment comprises determining a possible engagement efficiency of the target 22 by the directed-energy weapon 18; and a controller 16 arranged to, during an engaging phase, control the directed-energy weapon 18 to direct energy towards the target environment 20 (and more specifically, the target 22) conditionally upon the possible engagement efficiency.
  • an assessment system 14 arranged to perform an assessment of a target environment 20, wherein the target environment 20 comprises a target 22, and the assessment comprises determining a possible engagement efficiency of the target 22 by the directed-energy weapon 18; and a controller 16 arranged to, during an engaging phase, control the directed-energy weapon 18 to direct energy towards the target environment 20 (and more specifically, the target 22) conditionally upon the possible engagement efficiency.
  • FIG. 1 might relate to an apparatus 12 for a directed-energy weapon 18, the apparatus 12 comprising an assessment system 14 arranged to perform an assessment of a target environment 20, wherein the target environment 20 comprises a target 22, and the assessment comprises receiving data relating to a map of at least a portion of the target environment 20; and a controller 16 arranged to, during an engaging phase, control the directed-energy weapon 18 to direct energy towards the target environment 20 conditionally upon the data received.
  • an assessment system 14 arranged to perform an assessment of a target environment 20, wherein the target environment 20 comprises a target 22, and the assessment comprises receiving data relating to a map of at least a portion of the target environment 20; and a controller 16 arranged to, during an engaging phase, control the directed-energy weapon 18 to direct energy towards the target environment 20 conditionally upon the data received.
  • FIG. 1 might relate to an apparatus 12 for a directed-energy weapon 18, the apparatus 12 comprising: an assessment system 14 arranged to perform an assessment of a target environment 20, wherein the target environment 20 comprises a target 22; and a controller 16 arranged to, during the assessment, control the directed energy weapon 18 to direct energy towards the target environment 20 so that the assessment system 14 can perform the assessment using the directed energy.
  • an assessment system 14 arranged to perform an assessment of a target environment 20, wherein the target environment 20 comprises a target 22
  • a controller 16 arranged to, during the assessment, control the directed energy weapon 18 to direct energy towards the target environment 20 so that the assessment system 14 can perform the assessment using the directed energy.
  • FIG. 3 might relate to a method 100 of engaging a target 22, the method 100 comprising: during an assessment phase 102, performing an assessment of a target environment 20, wherein the target environment 20 comprises a target 22, and the assessment comprises determining a possible engagement efficiency of the target 22 by a directed-energy weapon 18; and during an engaging phase 104, controlling the directed-energy weapon 18 to direct energy towards the target environment 20 conditionally upon the possible engagement efficiency of the target 22.
  • FIG. 3 might relate to a method 100 comprising, during an assessment phase 102, performing an assessment of a target environment 20 by controlling a directed-energy weapon 18 to direct energy, wherein the target environment 20 comprises a target 22, and using the directed energy to perform the assessment.
