countermeasures device meaning in Chinese

对抗装置

Two kinds of improved design project are proposed : retrofocus project and image telecentric project . original structures are solved through gauss optics and primary aberration principle , and the aberration is optimized and analyzed too . to form staring opto - electronic countermeasure device , distributing of optical unit array is simply analyzed in the end
针对初始设计方案的不足,提出两种改进的设计方案:反远距方案和像方远心方案,通过高斯光学和初级像差理论求解出光学系统初始结构,利用光学设计软件进行像差分析和优化,并且对设计的光学系统组成凝视型光电对抗设备时光学单元阵列分布进行了简单分析。
