In last few years , people pay more attention to the distributed satellite sar system . this model system brings forward a new concept sar system 分布式星载sar系统是一种新的星载sar体制,它以小卫星群编队飞行,小卫星之间协同工作,共同完成单项或者多项任务。
In order to make satellite work on its own , the most important thing in research is realization of stable data transmission and management in satellite 小卫星要能实现自主工作需要稳定可靠的数据处理系统,因此实现星载机稳定的数据传输和管理是本课题的研究重点。
At last the concept of distributed microsatellites is introduced and some methods of moving targets detection and imaging based on distributed microsatellites are discussed 最后，对分布式小卫星的概念进行了介绍，讨论了基于分布式小卫星的运动目标检测与成像方法。
As the modern small satellite technique developing quickly , the multifunctional structure ( mfs ) technique is come out . the mfs technique is a new designed method of deep space detector 多功能结构技术是在现代小卫星技术飞速发展的情况下,而兴起的一种新的深空探测器设计方法。
Micro - satellites will be widely used in the fields of communication , remote sense and so on , with their properties of low volume and weight , low cost and easy - control 现代微、小卫星以其重量轻、体积小、价格低、易于控制等特点，得到了迅速发展，广泛应用于通信、遥感等领域。
Downconvertion and error control system based on concatenated code are the critical part of the leo spread spectrum communication system , and are widely used in the communication system 下变频和基于级联码的差错控制系统是该特种小卫星扩频通信系统的关键部分，并且在通信系统中有着广泛地应用。
If the rings persist then their supply of dust grains is being regularly replenished , and that almost certainly means that tiny moons within the rings are constantly shedding these particles 如果环是持久的，那么它们的尘埃就存在有规律的补给，这也就明确地意味着在环中的小卫星在不断的抖落这些颗粒。
It won ' t be gone forever . in about 60 years 2003 yn107 will lap earth again , resuming its role as a temporary , corkscrewing moonlet . in due course , other coorbitals will do the same 它不会永远离去。在大约60年后2003yn107会再次缠上地球，继续它的临时角色? ?螺旋运行的小卫星。其它的“同轨星”也会这么做。
Low power arcjet , which works between the power level of 100w and 1000w , is an ideal micro propulsion device of attitude control and nssk for small satellites and micro satellites 低功率的电弧加热发动机,即运行功率在100w ~ 1000w的电弧加热发动机,是完成小卫星、微型卫星轨道保持和姿态控制任务的理想推进系统。
On the base of active disturbance rejection control , author use active disturbance rejection control in small satellite attitude control system and designs a two - loop active disturbance rejection attitude control system 在深入研究了自抗扰控制理论的基础上,将自抗扰控制新技术应用于主动磁控小卫星姿态控制系统中。
