Title:Entomological Radar Signal Processing & Experimental Validation

Abstract: Insect migration is a significant ecological phenomenon in nature and massive insects do long-distance migration annually. Because most species of insect migrants are nocturnal to avoid their predators, it makes radar, with the advantages of all weather and all day work, to be the most effective tool to observe insect migration. Many important progresses have been made by entomological radars, such as high-density layering and common orientation. However, relative to group migration observation above, individual insect study becomes more and more important nowadays, which puts forward higher requirements on entomological radars. 

This presentation will focus on the entomological radar research for monitoring individual insect migration. To improve the entomological radar performance of individual insect monitoring, novel entomological radar is designed and proposed with several new technologies for species identification and trajectory analysis, including:

Insect body length/mass measurements based on multi-frequency RCS; 

Wingbeat frequency measurement based on micro-Doppler effect;

Orientation estimation based on instantaneous full-polarization system; 

Trajectory measurement using high-resolution phased array radar;

A series of experiments were carried out both in the anechoic chamber and the field, so as to validate the feasibility of these new radar techniques above, where 29 insect species were involved. Up to now, a Ku-band entomological radar prototype has been built with the high range resolution of 0.2m and the capability of instantaneous full-polarization measurement. The field observations were carried out in Langfang, Hebei Province, Xilinhot, Inner Mongolia, etc. The wingbeat frequency, head orientation and aerial density of migratory insects were successfully measured.
