摘要/Abstract

摘要： 为实现Ku波段昆虫雷达体型参数测量，基于全极化测量装置在微波暗室测量的昆虫数据，分析了Ku波段昆虫雷达散射截面积（Radar Cross-Secion，RCS）特性.发现大昆虫为谐振区散射，无法基于RCS反演体型参数.为保证雷达体型测量准确性，必须将大昆虫识别并剔除；为此，提出相对特征相位和RCS参数联合的大昆虫辨别方法.在此基础上，分析了中小昆虫体型与特征参数的关系，发现这些特征参数均能较好的反演昆虫体长/体重，从而给出Ku波段昆虫体长、体重反演经验公式.

Abstract: To measure the insect body size parameters for Ku-band entomological radar, based on the insect data measured by a fully polarimetric measurement rig, the RCS (Radar Cross-Secion) characteristic of insects in Ku-band is studied. It is found that the scattering of the large insects is in the resonance region. Thus, the body size parameters of the large insect cannot be estimated from the RCS. To ensure the accuracy of body size measurement, it is necessary to identify and get rid of large insects. For this reason, a large insect discrimination method based on the relative phase of scattering eigenvalues and one of the RCS parameters is proposed. The relationships between insect body length and mass and RCS parameters for the middle and small insects are analyzed. It is found that all parameters can be well used for estimating the insect body length and mass, and the empirical formulas for insect body length and mass estimation are obtained.

Key words: Ku-band, fully polarimetric entomological radar, large insect discrimination, body size estimation
