摘要： A compact, computationally-efficient, firmware-resident version of a DSP autocorrelation function, extracts periodic information from noise-corrupted signals. The function adapts autocorrelation parameters in real-time either autonomously or via up-link commands from a ground-based system. The function calculates specific determination values that optimize the performance of the autocorrelation process for a specific application. The per-bit multiplication used by the function can be performed by logically ANDing each of the respective samples in the two arrays. The summation of the per-bit multiplication is an integer summation, rather than the more time-consuming floating-point summation. A further aspect of the present function is the utilization of a threshold detection process to discretize the correlation output estimate to a one-bit binary sample.

摘要： Methods and apparatus for a fast action impulse thruster according to various aspects of the present invention may comprise a projectile comprising an impulse thruster system. The impulse thruster system may comprise a guidance system and a fast action impulse thruster system. The guidance system may control the trajectory of the projectile, for example by activating the fast action impulse thruster system to adjust the projectile's trajectory. The fast action impulse thruster system may be configured such that it may provide an impulse force to guide the projectile with a reaction time that is not affected by the rotational velocity of the projectile. The impulse force may be achieved by ejecting at least one mass from the projectile at high velocity such that a resulting momentum exchange may alter the trajectory of the projectile. The fast action impulse thruster system may also be configured in such a way so as to provide a significant improvement to the overall safety during the production, assembly, and handling of the projectile.

摘要： A munition is presented which includes an integrity verification system that measures the integrity of the munition. When an integrity threshold is not met, engagement of the munition with a predetermined target is aborted. Also presented is a methodology for gating the engagement of the munition with the target. The methodology includes performing an integrity check of the munition after it is deployed. The method further includes aborting the engagement of the target when the integrity check of the munition fails.
