摘　　要：研究多普勒及多普勒变化率对辐射源个体识别性能的影响,对多普勒及多普勒变化率对个体识别性能的恶化进行了量化分析,分析表明存在多普勒及多普勒变化率的情况下,用于个体识别的信号长度越长受多普勒的影响便越大。推导了多普勒对辐射源个体识别性能影响的表达式,给出了典型星载条件下可用于辐射源个体识别的信号长度,并针对常见调制类型进行了仿真分析。The influence of Doppler and Doppler rate-of-change on the performance of specific emitter identification（SEI）is researched.The performance deterioration of SEI caused by Doppler and Doppler rate-ofchange is analyzed and it is shown that under the condition of Doppler and Doppler rate-of-change,the longer length of the signal used for SEI and the more performance deterioration caused by Doppler.The expression of influence on the performance of SEI caused by Doppler is derived,and the signal length that can be used for SEI is given under the typical condition of satellite borne.Finally simulation verifications are carried out.
