中文摘要:

      现代武器装备单平台集成的各频段雷达、通信等无线电设备数量越来越多,且发射信号均向高功率、超宽带等方 向发展,使得雷达与其他设备之间的发射频谱交叠严重,进而导致不同设备之间存在严重的电磁干扰问题。文中针对不同 无线电设备收发信号之间的电磁干扰问题进行了分析,重点讨论了数字T/R 组件脉冲发射带外频谱分量的产生机理和改善 方法,提出了针对性的频谱控制措施,并在某雷达数字T/R 组件上开展了试验验证,证明了该频谱控制方法的有效性。

英文摘要:

      The number of radar, communication device and other radio equipment in various frequency bands integrated on a single platform of modern weapons is increasing, and the transmitting signals are developing to the direction of high power and ultral- wideband. The transmitting frequency spectrum between radar and other equipment overlaps seriously, leading to serious electromagnetic interference problems between different equipments. In this paper, the electromagnetic interference problems between transmitting and receiving signals of different radio equipments are analyzed, and the generation mechanism and improvement method of the out-of-band spectrum component of digital T/ R module pulse transmission are discussed. The specific spectrum control measures are proposed, and experimental verification is conducted on a certain radar digital T/ R module, proving the effectiveness of the proposed spectrum control method.
