| 摘 要： | 目标建模与特征信号仿真是雷达对目标进行探测与识别的重要前提和基础。针对宽带条件下大型舰船目标的雷达特征信号难以进行实测和缩比测量的难点，采用面元法对目标的雷达散射截面（RCS）进行了有效的预估，通过多频点RCS成像方法获得目标的一维距离像特征信号。给出了具体建模和仿真计算的实例，并进行了详尽的结果分析。

| Abstract: | Target modeling and signature simulation are important prerequisites and groundwork for the radar to detect and to recognize a target.Due to the difficult problems of actual measuring and scaling measuring for the signature of large-scale naval vessel under the condition to wideband,an effective approach of computing high-frequency radar cross section (RCS) to the naval ships based on the plate element method was presented in advance,and then the target's one dimension range profile was obtained by adopting multiple-frequency-point imaging method.The concrete modeling and simulation and calculating examples were illustrated and the experimental results were analyzed. |
