Trajectory shaping of an interceptor is crucial for numerous reasons, including the ability to specify the impact angle at which the target is intercepted, providing for example enhanced lethality and reduction of collateral damage. A new three-point trajectory shaping guidance concept against stationary targets will be presented in this talk, which is based upon the principle of constant inscribed angles in a circle. This new guidance concept enables imposing a required impact angle by traversing specific circular paths. The guidance concept was implemented using a simple controller, obtained from linearization around the required nominal circular trajectory. Implementation of the guidance law requires information of the inscribed angle only. Linear and non-linear dynamic models were compared through simulation, and results for various scenarios of applied desired impact angles will be shown. Kinematic trajectories for constant inscribed angle, derived analytically against moving targets, will be presented as well.

The talk will be given in Hebrew
