远景的发展过程1971年5月,也就是发射陆地卫星一号的前一年,我们参加了 ERIM 专题讨论会,无可否认,那时,我们对如何完成一个可行的地表测试系统并没有一个明确的设想,而且也没有弄清与这个设想有关的种种问题。我们当时力图完成各种领域的调查或试验,为此,考查了各种遥感方法的可行性和研究各种可能存在的测试平台。也就在这个时候,我们决定把希望寄托在著名的 B—17方法(也就是今天仍在某些试验中使用的方法)上。此外,我们还使用同温层气球模拟太空图象的分辨率,很幸运地发现了下列的新途径:
Long-term development process In May 1971, the year before the launch of Landsat 1, we participated in the ERIM Symposium. Undeniably, at that time, we did not have a clear idea of how to implement a viable surface test system But also failed to find out the problems related to this vision. At that time, we tried hard to complete surveys or experiments in various fields. To this end, we examined the feasibility of various remote sensing methods and studied various possible test platforms. It was also at this time that we decided to pin our hopes on the well-known B-17 method (that is, the method that is still used today in some experiments). In addition, we have also used stratospheric balloons to simulate the resolution of space images and are fortunate to find the following new avenues:
