A New Guidance Law for the Defense Missile of Nonmaneuverable Aircraft
TLDR
The results show that the performances of COIP and A-CLOS guidance laws are almost identical in a coplanar engagement scenario, but the COIP law has the additional advantage of working with only position information, without the knowledge of motion of the players.Abstract:
In this brief, a new guidance law for the defense missile of nonmaneuverable aircraft is formulated based on dynamic game considerations. First, a simple differential game of protecting a static target in 2-D, involving simple motions for the attacker and defender, is introduced. The analysis is then extended to a moving noncooperative target in 2-D, in view of the fact that a nonmaneuverable aircraft would not be able to cooperate with the defender. A heuristic solution for the game is proposed and tested, and the results of the 2-D analysis are then extended to 3-D to formulate a new guidance law for the defense missile called the command to optimal interception point (COIP) guidance law. The validity of the new guidance law is checked using trajectory and envelope simulations, built with high-fidelity 6-DOF models using the computer-aided design of aerospace concepts in C++ framework. Performance comparisons are shown between the COIP guidance law and the recently proposed airborne command to line-of-sight (A-CLOS) guidance law. The results show that the performances of COIP and A-CLOS guidance laws are almost identical in a coplanar engagement scenario, but the COIP law has the additional advantage of working with only position information, without the knowledge of motion of the players. In addition, in a noncoplanar engagement case studied, the defense missile is shown to achieve intercept using the COIP guidance law, but fails when using the A-CLOS guidance law.read more

I and i
TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.

Optimal Cooperative Pursuit and Evasion Strategies Against a Homing Missile
TL;DR: It is shown how the target can lure in the attacker, allowing its defender to intercept the attacking missile even in scenarios in which the defender's maneuverability is at a disadvantage compared with the attacking ballistic missile.

Cooperative Differential Games Strategies for Active Aircraft Protection from a Homing Missile
TL;DR: In this paper, a linear quadratic differential game formulation for arbitrary-order linear players' dynamics in the continuous and discrete domains is derived for a team composed of two agents, where the target aircraft performs evasive maneuvers and launches a defending missile to intercept the homing missile.

TL;DR: In this article, a cooperative guidance law for a defender missile protecting an aerial target from an incoming homing missile is presented, where the defender knows the future evasive maneuvers to be performed by the protected target and thus can anticipate the maneuvers it will induce on the incoming Homing missile.

TL;DR: In this paper, the authors defined the following components of an evasive maneuver component normal to the target-missile line of sight: amp, ad, am, target, defender, and missile lateral accelerations, respectively at max, ad max, am max, max, and am max = target, defenders, and missiles maximum lateral acceleration.
