中文摘要：
论述了利用新近研制的二维阵列开展基于数字电视信号的三坐标外辐射源探测实验的研究结果。结合数字电视信号的电波覆盖特征,首先论证了低空目标三坐标定位情况下仰角测量的必要性,接着阐述了接收阵列设计的原理和方案,并讨论了相应的仰角和方位角的估计策略及转换方法,最后重点介绍了实验开展的情况,包括系统配置、空中目标探测典型结果及分析,从实验角度验证了该三坐标数字电视外辐射源雷达方案的性能。
英文摘要：
The latest domestic experimental research of three-dimensional（3-D）passive radar based on digital television signal is decsribed using the newly-developed 2-D array.Based on the radio coverage characteristics of digital television,the necessity of elevation measurement under low-altitude target 3-D localization is investigated firstly.Then the principles and programs of receiving array design are briefly discussed,including the estimate and conversion of elevation and azimuth.Finally,the experimental progress is highlighted,involving system introduction,illustration and analysis of typical detection results of airplanes,which proves the feasibility of the proposed digital television based 3-D passive radar framework by field experiment.
