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 development of the technology level, the jamming pattern of the radar countermeasure system is progressing continuously, from the initial noise suppression jamming to the coherent dexterous jamming. Transmit-jamming is an efficient method of radar jamming, becoming more and more popular in radar jamming system. Based on the transmit-jamming of radar jamming background, this paper proposes a concept of constant-gain transmit, and compares the advantages and disadvantages with traditional constant-power jammer, theoretical derivations and calculation of constant-gain transmit system are also done. Then the effectiveness of typical operational objects is analyzed, the prospect of the application of constant gain transmit-jamming system is given at last.
