中文摘要 | 本研究旨在了解利用數位電視訊號為輻射訊號源之被動雷達目標特徵資訊提取技術之可行性。相較於類比FM廣播信號,數位電視信號具有更大頻寬,故可擁有更佳之距離解析度。此外,數位訊號在合理雜訊比可以正確解調而獲取無雜訊之參考訊號,提升被動雷達效能。本報告探討數位電視被動雷達之訊號處理流程,與國際間數位電視被動雷達技術之發展現況。 |
英文摘要 | Abstract A study is conducted on the feasibility of using the digital video broadcasting(DVB) signals as an opportunistic radiation source for passive radar target characteristics extraction. Compared to the analog FM radio signals, DVB signals have a greater bandwidth and an enhanced range resolution. In addition, since the DVB is a digital modulated signal, it can be demodulated perfectly at reasonable signal to noise ratios, resulting in a noise-free reference signal for passive radar usage. In this report, we discuss the signal processing flow of the DVB passive radar system, and the current worldwide technological development of passive coherent location radar based on DVB signals. |
