Abstract

The possibility of using long (multi-kilometer) tethers in orbit, particularly for passive radar surveillance, is examined. Such devices could use the echo derived from common UHF and VHF sources (primarily commercial radio and television stations) for target range and Doppler estimation. Such systems could provide high gain (50-60 dB) and high spatial resolution at low frequencies. Configurations, stability, and other problems associated with satellite tethers are discussed.<>

用于无源雷达系统的系留卫星天线阵列

研究了在轨道上使用长(多公里)系绳的可能性，特别是用于无源雷达监视。这种装置可以利用来自普通超高频和甚高频源(主要是商业无线电和电视台)的回波进行目标距离和多普勒估计。这样的系统可以提供高增益(50-60 dB)和低频率的高空间分辨率。讨论了卫星系绳的结构、稳定性和其他问题
