    摘要: An active sensing system includes an agent and at least one sensor operatively associated with the agent. The at least one sensor includes one or more emitters configured and disposed to establish a sensing zone. A conflict identification module is configured and disposed to identify one or more sensor conflict regions, and an active sensor controller is operatively connected to the at least one sensor and the conflict identification module. The active sensor controller is configured and disposed to form an adjustment zone within the sensing zone to accommodate the one or more sensor conflict regions.

    摘要: A system and method for optimizing transmission of radio frequency communication link signals in a radio frequency communications network comprises determining a statistical difference between a mean radio frequency communication link propagation loss value based on a set of measured radio frequency communication link propagation loss values, and a radio frequency communication link propagation loss model value; calculating a signal to noise ratio of a radio frequency communication link signal; computing a confidence interval based on a measured signal to noise threshold ratio of a measured radio frequency communication link signal, and a standard deviation associated with the calculated signal to noise ratio; assigning a probability value based on the confidence interval; and generating a radio frequency communication link packet completion rate performance level based on the probability value. The transmission of radio frequency communication link signals occurs in either jamming or no jamming situations.
