摘　　要：在有限地域范围内使用多个超短波网络极易产生网间互扰，影响正常通信。文章从超短波网络的网间地域关系人手，从频率复用的角度，建立网间干扰数学模型，用虚拟扩展的方法，通过网间干扰矩阵描述网络互扰，为超短波网络频率规划提供参考。Improper frequency allocation will cause mutual interference when many VHF wireless networks are used within a specified region, and may destroy normal communications. Based on the relationship among VHF networks, this paper first calculates the distance of frequency reuse, and then builds an interference mathematical model based on the main modes used in VHF networks. After that, it makes virtual expansion for one network which uses many frequencies, and finally represents the interconnection mutual interference by interference matrix. The conclusion of the paper provides support for frequency planning and optimization for VHF wireless networks.
