摘要
机载预警雷达是预警机的主要探测设备,具有发射功率大、占用频带宽的特点,与预警雷达处于同频段工作的IFF系统易受其干扰。本文依据预警机作战应用时的电磁环境,分析了可能的干扰来源,和预警雷达脉冲信号对IFF系统的邻频干扰。并以误码率和应答次数为指标,在不同雷达工作参数条件下仿真了IFF受干扰的程度。模型对于其它无线系统在不同场景下的邻频干扰及共存研究具有较强的扩展性。
Airborne early warning radar is main detection equipment of an early warning plane, it features high transmitting power, wide occupied frequency band, the IFF system which is in the same frequency band as the early warning radar is easily interfered by the early warning radar. The article analyzes possible interference sources, and adjacent frequency interference of the early warning radar pulse signal for the IFF system in accordance with the electromagnetic environment of early warning plane in operations. The interfered degree of the IFF is simulated in different radar operating parameters with error code rate and response times as indexes. The model has strong extendibility for adjacent frequency interference and coexistence study of other wireless systems in different scenes.
