摘　　要：通信与通信对抗攻防双方都十分关注信号在空间信道中的传输特性,这对于对抗效能的影响极其巨大。针对三类视距无多径空间信道中信号传输的衰减特性进行了定量的分析与对比,展现了采用高增益天线定向窄波束互指的通信双方所具有的较强反侦察与抗干扰能力;而且阵列天线波束方向图固定方向置零与自适应调零从理论上为通信收发双方提供了更强的通信电子防御手段。所以为了提升侦察干扰的有效性,通信对抗必然会向分布式协同方向发展,这样才能实现对抗博弈的平衡。所揭示的上述技术演变趋势为通信对抗的未来发展规划研究提供了重要参考。Both communication and communication countermeasures pay more attention to the signals transmission character-istics in space channels,which have a significant impact on the effectiveness of communication countermeasures.The signal trans-mission attenuation characteristics in three types of LOS(Line of Sight)non-multipath space channels are quantitatively analyzed and compared,and the strong anti-reconnaissance and anti-jamming capabilities of both communication parties using high gain an-tenna directional narrow beam mutual pointing are demonstrated.The fixed direction nulling and adaptive nulling on array antenna beam pattern theoretically provide stronger communication electronic defense approaches for both the communication transmitter and receiver.In order to improve the effectiveness of reconnaissance and jamming,communication countermeasure will inevitably develop for the distributed coordination to achieve the balance of game countermeasure.The above revealed technique evolution trends provide an important reference for the future development planning of communication countermeasures.
