摘要
雷达为了快速识别目标,需建立相应的目标特性库,现有的得到目标特性的方法有实测法和仿真法,实测法耗时耗力又耗钱,不能大量使用。而目前的仿真方法将电磁计算和成像分开进行,不利于快速及准确成像。本文使用MATLAB编写成像系统,通过后台调用FEKO,将FEKO建立的模型计算远场来模拟回波,将计算结果成一维距离像和二维ISAR像,从而大大提高了成像速度和精度。
The radar needs to build up homologous database of target characteristic for quickly identifying a target, presently methods of getting target characteristic that actually measure and imitate,actually measuring method are consume and expensive,can't use in great quantities.But currently imitating method separates computing electromagnetism to imaging, become disadvantage in fast and exact imaging.This text compiles imaging system using MATLAB,which computes a far field using the target that is built up though the FEKO to emulating echo from a backstage with the FEKO,and use the result of calculation to image one dimensional distance imaging and two-dimensional ISAR imaging,thus consumedly raises speed and accuracy of imaging.
