摘要/Abstract

摘要： 双基地雷达观测下，锥体目标的微动特征可以由顶部局部型散射中心，底面边缘滑动型散射中心和侧面滑动型散射中心的微多普勒来表述.首先，本文建立了三种类型双基地散射中心的微多普勒统一参数化模型；然后，提出滑动系数概念，即采用参数化模型两个参数的比值来定量评价散射中心的滑动特性，从而判别锥体目标上散射中心的类型；最后，通过电磁仿真验证了该参数化模型的准确性以及散射中心类型判别方法的可靠性，对锥体目标识别具有重要意义.

关键词: 双基地雷达, 锥体目标, 散射中心, 微动

Abstract: In the bistatic configuration,the micro-motion features can be represented by three types of scattering centers,the localized scattering center located at the target tip,and the two types of sliding scattering centers sliding along the target bottom edge and on the target side face.In this paper,the micro-Doppler of three types of scattering centers is firstly represented by a unified parametric model.Then,the sliding coefficient is defined by two parameters of the parametric model,and it is applied to discriminate scattering center types.At last,electromagnetic simulation results demonstrate that the micro-Doppler parametric model is precise,and the presented sliding coefficient is a reliable feature to recognize the cone-shaped targets.

Key words: bistatic radar, cone-shaped targets, scattering center, micro-motion
