| 摘 要： | 针对现有仿真研究对象多为简单目标,由此得到的研究结论不能简单地移植到复杂目标上这一问题,计算电磁学的全波数值算法———合元极,融入到微动复杂目标回波模拟中.以球头锥结构目标为例,研究了金属、涂敷球头锥在不同微动、极化方式下的微多普勒特征.研究表明,极化方式和涂敷影响了微多普勒信号亮度变化,但微多普勒频率变化规律保持不变,此研究工作可对弹道导弹探测、识别应用提供一定的量化参考.

| Abstract: | Present simulation method for micro-Doppler characteristics or approximate method of scattering computation is generally based on point-target model and its research result by these methods is hardly suitable for extended targets. For this reason, a simulation approach based on a powerful full-wave numerical method, hybrid FE-BI-MLFMA, is presented in this paper. By taking blunt-nosed cone target as an example, micro-Doppler characteristics of a conducting cone target and a head-coated cone target, under di... |
