摘　　要：对车载通信直扩电台的主要共址干扰类型进行分析,并指出共址干扰对车载通信直扩电台的影响。以共址干扰判据为基础,对共址干扰与电台上装规模和通信距离的关系进行了量化分析。在此基础上提出解决共址干扰的具体措施,为多部直扩电台共址配置时的电磁兼容问题和抗共址干扰能力的提升提供可靠的理论依据。Several primary types of cosite interference for vehlclel DSSS radios were analyzed,and the effect of cosite interferertce was also indicated. On the basis of the judgement of cosite interference,the quantificational conclusion about the installation scale of radios and link ranges is accomplished. The work of the paper provided a theoretic suggestion of the assemblage and application of vehiclel DSSS radios.
