A Novel Radar Detection Method for Sensing Tiny and Maneuvering Insect Migrants

A Novel Radar Detection Method for Sensing Tiny and Maneuvering Insect Migrants

The use of radar to monitor insect migration is of great significance for pest control and biological migration mechanism research. However, migrating insects usually have small radar-cross-section (RCS) and are accompanied by maneuvering. The current radar detection algorithms mainly have contradic...
