외부요인이 안티드론 재밍에 미치는 영향 연구

Abstract

This study is a follow-up study of Kim et al.(2018) police anti_drone empirical study that reported success rate of malicious_drone anti_jamming from 93% to 98%. Therefore, the purpose of this study is to investigate the influence of external factors on the anti_drone jamming by exploring 2~3% of the anti_drone jamming failure factors based on external factors, and to provide information on anti_drone jamming performance improvement and operation practice. Therefore, the study method should be based on the frame of reference of external factors (wind speed, cloud amount, humidity) and T test. As a result of the analysis, the average success rate of anti_drone jamming by model and type, the days with a wind speed of more then 8㎧, was 0.04 at alow rate and 0.129 at most, the days above more than below 3.5 the cloud amount, was 0.02 at alow rate and 0.218 at most, the days above more than below 65% the humidity, was 0.03 at alow rate and 0.243 at most, respectively. In the confidence interval estimating the likelihood of the actual population average at 95% confidence interval, the success rate of the anti_drone jamming by model and type, the days with a wind speed of more then 8㎧, was –0.2144 at alow rate and 0.007 at most, the days above more than below 3.5 the cloud amount, was 0.003 at alow rate and 0.2732 at most, the days above more than below 65% the humidity, was 0.003 at alow rate and 0.3161 at most, respectively. The external factors such as wind speed, cloud amount, and humidity were found to affect anti_drone jamming in both mean and 95% confidence interval. the effect was inversely proportional to the wind speed, was marked as proportional to the cloud amount, humidity, respectively.
