随着技术水平的不断发展,雷达对抗系统的干扰样式不断进步,从最初的噪声压制干扰发展到相参灵巧干扰。转发式干扰作为一种高效的干扰样式,越来越多地应用于雷达对抗系统。文中以雷达干扰中的转发式干扰为背景,提出了恒增益转发的概念,将其与恒功率的传统干扰机进行了优缺点对比,并对系统转发增益这一关键指标进行了理论推导和计算,从而对典型作战对象进行了有效性分析,最后对恒增益转发干扰系统的应用提出了展望。
With the constant development of the technology, the interference pattern of the radar countermeasure system is constantly improving, from the initial noise suppression interference to the coherent glitch interference. As a highly efficient interference pattern, transponder interference is increasingly used in radar countermeasure systems. In this paper, the concept of constant gain forwarding is proposed based on the background of the jamming in the radar jammer. The advantages and disadvantages of the traditional jammer with constant power are compared. The key index of the system gain is deduced and calculated theoretically , So as to analyze the validity of the typical combatant. Finally, the prospect of the application of the constant gain retransmission jamming system is put forward.
