Power Choices Rise for UAVs

　　無人駕駛飛行器（UAV）已成為軍事基礎設施的重要組成部分，以越來越多的形式從武器運載平臺，以更小的和難以跟蹤的單位主要用于監(jiān)視和情報收集。無人機平臺具有很強的適應性，允許使用不同的傳感器類型，如圖像傳感器和攝像機，以及光譜儀和化學傳感器的復雜的分析，使用高光譜成像和傳感器融合。

　　The wide variety of requirements results in a large number of choices that need to be made when analyzing power requirements and the ways in which the power can be delivered. Image-processing and sensor-fusion solutions tend to imply a need for large amounts of processing power， adding to the overall power requirements of the UAV. Although， some functions can be offloaded to ground stations for systems where the captured data is unlikely to be jammed or intercepted over the air， and where the latency of a round-trip processing delay can be tolerated. The image processing may be split such that simpler techniques used primarily for navigation can be kept on the airborne systems but more sophisticated analysis， primarily for use by ground troops or intelligence services， is offloaded via radio communications.
