摘要
雷达工作在日趋复杂的电磁环境中,同频干扰问题影响甚重。论文主要从理论上阐述了同频干扰产生的机理,推导出各雷达参数与同频干扰的关系,并进一步从理论和实际雷达接收回波的现象上分析同频干扰的特征以及其对雷达性能的影响,为如何设置雷达参数可避免干扰和抑制同频干扰算法提供理论支撑。
With the increasing number of radars and the increasing complex of EMC environment, the co-channel inter- ference between radars become serious. In this paper, the producing mechanism of co-channel interference is stated in theory, and the connection between co-channel interference and radar parameters is calculated, furthermore the characteristics of co- channel interference are analyzed both in theory and real radar echo. This paper reveals the co-channel interference effects on radars＇ capability, and tells people how to set radar parameters and design anti-interference algorithms.
