摘　　要：以我国上空的数字电视直播卫星信号作为研究对象,从信号产生方式,频谱特性,模糊函数时延维和多普勒维特性、系统链路预算出发,详细分析其用于无源雷达的性能。理论分析和实测结果表明基于数字电视直播卫星信号的无源雷达具有良好的目标探测能力。The digital video broadcasting-satellite（ DVB-S） signal over China is selected as the research object. The performance of passive radar is analyzed from the perspective of signal generation mode,spectral characteristics,delay dimension and Doppler dimension of self-fuzzy function,and system link budget. Theoretical analysis and experimental results demonstrate that the passive radar based on DVB-S signal has good target detection capability.
