A new guidance law for homing missiles

Abstract: this paper presents a new type of guidance law for homing missiles. The design concept is based upon the minimization of time duration for homing. It is shown that to realize this guidance concept an algorithm to predict the collision course and a guidance command generator to turn the heading of the missile toward the direction of the predicted collision course are necessary. A prediction algorithm for the collision course is derived and the realized overall guidance law is shown to be easily implementable. Simulation results are given to demonstrate the minimum time behavior and the widened launching envelope.

Device for guiding a missile

Abstract: The invention relates to a device for guiding a missile (1; 30) with a missile tip (2) and a cylindrical section (3) adjoining the tip of the missile; the device is provided with at least one control block (4; 31, 32) with exhaust openings (13-15) of corresponding nozzle bodies (10-12) arranged perpendicularly in relation to the missile's surface. In order to accomplish effective guidance, particularly of high-speed missiles (1; 30), in a simple and cost-effective manner it is proposed that the control block (4; 31, 32) be constructed with a plurality of small, fast-burning rocket motors (7-9; 33-36) that are arranged radially on the missile's periphery (1; 30) and that are ignitable in a predeterminable sequence and number.

Passive aircraft and missile detection device

Abstract: This invention offers the capability to passively detect and classify missiles, aircraft, and units with gas turbine engines and rocket motors. It does so by measuring the electromagnetic radiation from ions in the exhaust gas. These emissions are low in frequency and propagate beyond the visual horizon with little attenuation other than through wavefront spreading in the earth-ionosphere waveguide. Acoustic and mechanical processes in combustion chambers and turbines modulate the ion signals in a deterministic manner that makes the engine type classifiable. The proposed passive detection and classification device can sense and identify aircraft, missiles, and potentially ground vehicles and gunfire. This capability will reduce vulnerability of forces to threats and reduce fratricide among friendly units.

Decision-Directed Adaptive Estimation and Guidance for an Interception Endgame

Abstract: A new integrated estimation and guidance design approach is presented as a computationally effective procedure for interception of maneuvering targets. This is an adaptive approach that uses the following elements: banks of state estimators, and guidance laws, a maneuver detector for the onset of the target’s maneuver, and a hierarchical decision law for online selection of the estimator/guidance law pair to be employed. Simulation results confirm that the adaptive approach leads to a reduction in the miss distance as compared with cases in which only a single estimator/guidance law combination is available. LTHOUGH the study presented in this paper was motivated by a future ballistic missile defense (BMD) scenario, it addresses a more general problem, namely, the interception of a randomly maneuvering target by a guided missile in an environment of noise-corrupted measurements. The missile guidance endgame is an imperfect information terminal control problem with a very short horizon and it requires a design approach different from the one used in other control systems. In the classical approach, a linearized model of the dynamic process about a nominal set point is first derived. For this linearized model, the estimator and the control law are designed independently. The separate design is based on assuming the validity of the certainty equivalence principle (CEP) and the associated separation theorem (ST). 1
