This disclosure provides systems, methods, and apparatus for intercepting a moving target by a plurality of interceptors that individually have insufficient capability to achieve intercept. An electronic processor can receive information corresponding to a state of the moving target at a first time. The electronic processor can determine a plurality of hypotheses for the future maneuvers of the moving target. The hypotheses can be based in part on the state of the moving target at the first time and the location of any defended assets. The electronic processor can assign a respective target maneuver hypothesis or set of hypotheses to each of a plurality of interceptors. The electronic processor can assign firing times and/or initial guidance commands to each interceptor. The electronic processor can control each interceptor to maneuver such that the moving target is intercepted, based on the respective target maneuver hypotheses.

Multi-hypothesis fire control and guidance

A load relief system for a launch vehicle including a wind sensing system responsive to wind speed and direction at selected locations for providing an output of sensed wind speed and wind direction at the selected locations, a plant model responsive to the sensed wind speed and direction within a finite horizon, a current state of the launch vehicle, and control commands of the launch vehicle to predict the trajectory of the launch vehicle, an error circuit responsive to the predicted trajectory and a reference trajectory to produce a trajectory error, and an optimizer responsive to the trajectory error and configured to provide control commands to compensate for wind load over the finite horizon of the launch vehicle by reducing the total angle of attack.
