一、概述多点相关定位技术从验证到使用已经有几十年的历史了。这项技术采用多个地面站,通过计算各站到达时差(TDOA)进行目标定位。它最早被用作军事用途来精确定位航空器位置,在空管监视领域最初主要用在机场场面监视方面,作为场面监视雷达的一种补盲手段。 First, an overview of multi-point positioning technology from verification to use has been decades of history. This technology uses multiple ground stations to target location by calculating TDOA. It was first used as a military purpose to pinpoint the location of an aircraft and was initially used primarily in the field of air traffic surveillance as a proxy for scene-monitoring radars.
