Insect migration is a significant ecological phenomenon in nature, and difficult to directly
observe because insects are small and fly hundreds of meters above the ground at night …

The implementation of precision farming technologies into agricultural practice requires,
among other things, precise determination of the extent and intensity of insect infestation in …

Continental coverage and year-round operation of the weather radar networks provide an
unprecedented opportunity for studying large-scale airborne migration. The broad and local …

The length and width of insect body are critical parameters for entomological radar species
identification. However, the body width is not measurable in entomological radar currently. In …

For insect radar observations, exploiting radar echoes from insects to accurately estimate
size parameters, such as body mass, length, and width of insects, can help to identify insect …

Accurate monitoring of locust migration is the basis for early warning and emergency control
programs. This article integrates laboratory recordings with the use of Ku-band vertical …

Dear editor, The unmanned aerial vehicle (UAV) is a popular aerial instrument in both
military and civil fields [1]. Radar is an efficient tool for aerial target surveillance and target …

For radar observations, invariant target parameters extracted from the scattering matrix (SM)
provide information about the target's geometry and composition. By studying the invariant …

Insect migration provides major ecosystem services, and sometimes, migratory pests cause
serious crop damage and yield loss. Species identification is critically important in studies of …

Current vertical-beam entomological radars record the polarization direction corresponding
to the maximal ventral-aspect radar cross section (RCS) as the insect's orientation. For so …
