Collaborative Weapon-Target Web Engagement Tactics in Stability Regions

Laser or GPS guided seeker algorithms override the nonlinear control algorithms to acquire and strike the target. They are a one-to-one weapon-target acquisition technique dependent strike. Further, the combat pilot in short range targets is required to coordinate with the fire control system, acquisition, engagement, etc., all simultaneously that are time critical for both human and the machine. Current trends in Cooperative Autonomy of weapons to strike a target-web demand loitering control algorithms onboard weapons until the human intelligence prioritize a target-web. For the human controller in this process, prioritization does not guarantee acquisition for a seeker algorithm to be active. Thus, there is a need to study extended stability region-based nonlinear control algorithms to work in conjunction with the seeker algorithms. Unfortunately, stability regions in which the weapons need to reside is an ambiguous problem prompting industries to discover more and more sensor innovations for a given airframe of the weapon. In one of the reviews of the SMARTOOLS publications, SpaceX is known to utilize extended stability region optimizers for its boosters to land on the targeted geo-coordinates. Target-web acquisition problem is similar in nature as far as stationary targets are concerned. The rationale of SMARTOOLS is to engage these revolutionary sensor and airframe platforms along with the stability regions, wherein, weapons can cooperatively acquire target-web through machine intelligence and strike by activating seeker algorithms. Thus, launch is assumed from F-15EX’s with dozen missiles (assume they are a combination of Laser and GPS guided) or from F-16 or F-35’s four missiles on its carriage in addition to their bombs.  SMARTOOLS is confident in developing these new approaches by using the results it has. It provides a Nyquist like plot in time domain when the state-space model that derives transfer function matrix for the plot is uncertain or varying. This theory is friendly to determine extended stability regions for a nonlinear weapon when model and control parameters are either uncertain or orchestrated (patent pending, July 7, 2020). The concern in our context is, how a stability region-based loitering control algorithm after an inputted target-web is acquired would activate the seeker algorithm for a target-web strike? While the seeker algorithm is known to guarantee autonomy or semi-autonomy for a target-web strike, cooperative loitering algorithms in stability regions would guarantee acquisition for seeker to be effective. It is the novelty of this proposal. The stability margins supplement commands. Specifically, phase margin is command input-specific which will be utilized for the target-web acquisition in the stability regions.
