Insect speed extraction method based on a high resolution and full polarisation radar with vertical-looking mode

Abstract

This study introduces a novel insect speed extraction method based on a high resolution and full polarisation radar with vertical-looking mode. The insect echo model of the high resolution and full polarisation radar is first established. Then, an iterative algorithm for estimating the horizontal speed of insects is derived based on the second-order polynomial approximation. Finally, experimental results show the effectiveness and feasibility of this algorithm in extracting the horizontal speed of insects. Compared with the traditional method, the method here is more simple and effective and greatly reduces the computation.
