Abstract
Radar has been used to study insect flight for over 20 years. Radar, especially airborne radar, is unrivaled in its ability to observe the spatial organization of insect migration. This paper reports methods of data collection and analysis used by current airborne entomological radar systems and, in particular, the method used to review the data collected and visualize any large-scale structures detected. Examples of data from recent U.S. Department of Agriculture field experiments are presented to illustrate the analysis techniques. The data review method allows further data collection and analysis to be focused on areas of particular interest and thus significantly enhances the utility of airborne entomological radar.
