    摘要： A radar sensing system for a vehicle includes a transmitter, a receiver, and an interference mitigation processor. The transmitter transmits radio signals. The receiver receives radio signals. The received radio signals include reflected radio signals that are each transmitted radio signals reflected from objects in the environment. The receiver also down-converts and digitizes the received radio signals to produce a baseband sampled stream. The interference mitigation processor produces a second received radio signal that includes reflected radio signals that are transmitted radio signals reflected from a first object. The interference mitigation processor uses the second received radio signal to remove selected samples from the baseband sampled stream that are attributed to radio signals reflected from the first object to produce a modified baseband sampled stream. The receiver uses the modified baseband sampled stream to detect a second object more distant than the first object.

    摘要： A method, system and computer readable media for route re-planning including generating enemy force movement predictions to be used during mission planning. During a mission, enemy force movements can be compared to the predictions. By using enemy force movement predictions for an initial comparison, the enemy force movements may only need to be compared to the own force mission plan if the enemy forces deviate from the predictions. When enemy force movement deviates from the predictions, new enemy force movement predictions can be generated. The new enemy force movement predictions can then be compared to the own force mission plan to determine if a route re-plan is needed. The route can be re-planned to determine a route that reduces or eliminates the chance of a lethal encounter with an enemy or threat.

    摘要： A driving assistance apparatus mounted to a first vehicle is provided as follows. A situation determination section determines whether a situation requires compromise between the first vehicle and a nearby vehicle. A target vehicle specification section specifies a second vehicle as a target vehicle that requires compromise with the first vehicle. A scheduled action specification section specifies a scheduled action content of the first vehicle when the situation requiring compromise is determined by the situation determination section. A transmission processing section transmits the scheduled action content specified by the scheduled action specification section to the second vehicle. A reception processing section receives acceptance and refusal information indicating acceptance or refusal of the scheduled action content from the second vehicle. A notification processing section issues a notification indicating whether the driver of the second vehicle accepts the scheduled action content, based on the received acceptance and refusal information.

    摘要： There is provided a radar apparatus of an electronic scan type configured to transmit an electric wave and calculate an angle of a target based on a phase difference of respective reception signals, thereby detecting a target position. An antenna unit transmits and receives the electric wave and provided with two transmission antennae. A transmission unit alternately transmits an electric wave having a first beam pattern and an electric wave having a second beam pattern from the two transmission antennae. First and second reception units calculate arrival angles and reception levels of reflected waves calculated from respective reception signals which are obtained by receiving the reflected waves by the first and second beam patterns. A comparison unit compares the reception levels by combining the arrival angles of the reflected waves. A determination unit determines whether a target actually exists at the arrival angles in accordance a comparison result.
