摘　　要：针对车载跳频电台的共址干扰问题,首次进行了全面、深入的研究,并构建了软件分析平台;首先对共址干扰的一般模型进行研究,确定了影响共址干扰的主要影响因素;接着,从实验和理论两方面出发,分别对天线耦合、电台收发信机模型、安全带宽进行了研究,结合电台组网方式提出了基于安全带宽的跳频误码率计算方法;在此基础上,通过建立数据库管理平台、引入优化算法,设计开发了共址干扰分析软件平台,实例分析表明平台对研究共址电台性能并提出改进建议具有重要作用。For the cosite interference （CI） problem of vehicular frequency--hopping （FH） radio, a comprehensive and in--depth research is conducted for the first time, and a software platform is established. Firstly, main influence factors of CI are confirmed through analyzing the general model. Then, from two aspects of experiment and theory, antenna coupling, transceiver model and security bandwidth are inves- tigated, combined with networking mode, a FH BER computation method based on security bandwidth is proposed. On the basis of the study above, through establishing database management platform and introducing optimization methods, the CI analysis software platform （CIASP） is constructed and designed. The example analysis shows that the CIASP is important to investigate the performance of cosite radio and propose suggestions for improvement.
