摘要
在视通条件差、电波传播环境恶劣的导弹发射战场,通过成熟的无线局域 (WLAN)技术实现手持计算机和战场无线信号发送设备的局域网通信,经频率转换后将信号发送至中频转发设备,转发设备分析数据后发送至维修中心接收设备,维修中心接入已有广域网。根据距离和实际环境不同,中心和战场间可以采用直通、1次转发或 2次转发方式通信。信号发送配置了 4个工作频点,采取直扩、跳 /扩结合的多种抗干扰方式和按需分配的信道分配策略,保证信号传输的有效性和安全性。
At the missile launching site with bad communication environment, wireless communication between palmtop computer and wireless signal sending device can be implemented by mature WLAN technology. After that frequency transformation signal is sent to receiver which is connected to existing WAN in maintenance center. According to different distance and actual environment, we can adopt direct, transmitted once or twice mode to implement communication . In order to ensure validity and security of signal transmission, four frequency working points are used,and several measures of anti-jamming and mechanization are adopted, and distribution of channels according to need strategy is used.
