SUMMARY:Cooperative Guidance Law For Intra-salvo Tracking
DESCRIPTION:Lecturer:Nadav Balhance\n Faculty:Department of Aerospace Engin
 eering\n Institute:Technion – Israel Institute of Technology\n Location:
 Classroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abstrac
 t: \n Details: \n The use of multiple interceptors against a single target
  is an effective way of increasing the chances of success of an intercept.
  The basic method is salvo shooting\, in which each interceptor is indepen
 dently guided toward hitting the target.  With the growth of computers pr
 ocessing power and the developments in communication capabilities of moder
 n interceptors\, the alternative approach of using interceptors that coope
 rate with each other in order to complete the common intercept mission is 
 becoming a more promising and attractive solution. In order to cooperate\,
  the interceptors should communicate. The communication ability among the 
 interceptors is strongly related to the geometric configuration of the eng
 agement\, especially if the communication is achieved by the use of unidir
 ectional antennas.\nIn this seminar we will present three cooperative guid
 ance algorithms for the case where two interceptors pursue a single target
 \, while constraining an additional geometric condition. The geometric con
 dition is to preserve the relative look angle between the interceptors aro
 und some constant reference values during the engagement. This kind of geo
 metric condition enables the cooperating interceptors to communicate with 
 each other even with the use of unidirectional antennas.\nWe will begin th
 e talk with some background and presentation of the guidance problem\, fol
 lowed by a formulation of the guidance problem as a linear quadratic optim
 al control problem. We will then present its solution considering two situ
 ations: when reference values for the relative look angles are given\, and
  when they are free and can be chosen to improve the performance of the gu
 idance law. To summarize the talk\, we will present numerical examples\, w
 hich demonstrate that applying the proposed guidance algorithms\, enables 
 to achieve the additional geometric condition without substantially affect
 ing the miss distance and with a reasonable control effort. A comparison b
 etween the proposed guidance algorithms will be presented as well.
