The present study has made an attempt to test one of the most important law in Bibliometric studies i.e. Bradford’s Law of Scattering. It describes the quantitative relation between journals and articles. In this study, a total of 3433 articles were retrieved from Web of Science database during the span of 2008-2017, covered in the field of Drone Technology. Data analysed with respect to relative growth rate and doubling time of literature. It is calculated and scattered all 3433 articles in 1155 journals. It reveals that Journal of Intelligent & Robotic System secured top position with the highest number of publications 140 (4.08%), followed by Remote Sensing with a share of 127 (3.70%) and Sensors occupied the third position with 101 (2.94%) publications. Top ten ranked journals have 682 (19.86%) publications out of 3433 publications of total output. The journal distribution as per Bradford’s law reveals the ration as 32:195:928 in drone technology, dispersion of journal titles in drone technology does not satisfy Bradford’s law of Scattering in theoretical aspect. But tested through Leimkuhler model, it is found fit the data for the Bradford Multiplier (k) at 3.85.
