摘要

星链是无源雷达的新选择之一，该系统包括两个非地球静止轨道(NGSO)星座，为最终用户提供高速互联网。本文研究了利用卫星发射信号作为无源雷达探测机载目标的机会照明源的可行性。考虑了卫星链路功率预算、可探测时间和距离以及长时间积分(LTI)过程中产生的多普勒偏移三个方面。此外，还将星链获得的结果与基于gnss系统的结果进行了比较，以了解相对的优缺点。结果表明，基于星链的系统在机载目标探测中具有一定的应用潜力。

Feasibility of Starlink Transmissions for Passive Airborne Targets Detection

Starlink is one of the new option for passive radar, which is a system including two Non-Geostationary orbit (NGSO) constellations, to provide high speed internet to end-users. In this paper, the feasibility of using these satellite emissions as illuminator of opportunity (IoO) for passive radar to achieve the detection of airborne targets is investigated. Three aspects are taken into consideration: satellite's link power budget, detectable time and range and Doppler migrations generated during long time integration (LTI). In addition, results obtained from Starlink are compared to those of GNSS-based system to gain an appreciation of relative merits and drawbacks. The results show that Starlink-based system has a certain potential in the application of airborne targets detection.
