本文介绍的一种按轨道参数对苏联照相侦察卫星分类的方法简便易行。这种方法是在对苏联从1974年至1979年发射的200颗照相侦察卫星的轨道资料进行分析研究的基础上作出的。根据这200颗卫星的轨道特点,对它们进行分类的结果与按遥测信号进行分类的结果基本一致。由于目前苏联照相侦察卫星的技术状态与1974年至1979年这一阶段基本相似,因此,这种轨道参数分类法对目前苏联照相侦察卫星也应该是基本适用的。有兴趣的读者不妨用这种方法对近一、两年来苏联发射的卫星试一试。随着苏联侦察卫星计划的进一步推进,特别是当更新的一代照相侦察卫星进入空间时,由于卫星轨道的相应变化,这种按轨道参数分类的方法理应作相应的修改。或者是对该方法的判据数值e_1、V_1和V_2加以修改,或者是改变检查的准则或换用别的轨道参数。本文是根据国外资料改编的。为了使读者对这种分类法有更透彻的了解,改编者补充了一些说明,并对这种方法的长处与局限性提出了看法。
This article presents a simple and easy method to classify Soviet reconnaissance satellites by orbital parameters. This method was based on an analysis of the orbital data of 200 photographic reconnaissance satellites launched by the Soviet Union from 1974 to 1979. Based on the orbital characteristics of these 200 satellites, the results of their classification are basically the same as those classified by telemetry signals. Since the technical status of Soviet reconnaissance satellites is basically similar to that of 1974 to 1979, the orbital parameter classification should be basically applicable to the current Soviet reconnaissance satellites. Interested readers may wish to use this method to test the satellites launched by the Soviet Union in the past one or two years. With the further development of the Soviet reconnaissance satellite program, especially when the newer generation of photographic reconnaissance satellites entered space, this method of classification by orbit parameters should be modified accordingly due to the corresponding changes in satellite orbit. Or the method of determining the value of e_1, V_1 and V_2 are modified, or change the inspection criteria or use other track parameters. This article is based on foreign information adapted. In order to give readers a more thorough understanding of the taxonomy, the editors supplemented some of the notes and offered their opinion on the strengths and limitations of this approach.
