高技术条件下,侦察卫星可在高空上百公里外的轨道上严密地监视目标,而不受国界和地理条件的限制。遥感技术的飞速发展及其在侦察领域的广泛运用,加之传统的侦察技术、手段的继续作用,不仅使侦察的面积更大、范围更广、速度更 Under high-tech conditions, reconnaissance satellites can closely monitor their targets over orbit at altitudes of hundreds of kilometers without being bound by national boundaries and geographical conditions. The rapid development of remote sensing technology and its extensive use in the field of reconnaissance, combined with the continuing role of traditional reconnaissance techniques and means, not only make the reconnaissance area larger, wider and more speedy
