The latest domestic experimental research of three-dimensional (3-D)passive radar based on dig-ital television signal is decsribed using the newly-developed 2-D array.Based on the radio coverage characteris-tics of digital television,the necessity of elevation measurement under low-altitude target 3-D localization is in-vestigated 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 feasibili-ty of the proposed digital television based 3-D passive radar framework by field experiment.
