两种干扰方式对雷达脉冲压缩技术的影响

The Effect of Two Jamming Methods upon Radar Pulse Compression Technique

在简要介绍了雷达脉冲压缩技术常用的相关处理和全去斜处理技术后,详细分析了在雷达波段相同时,这2种技术适用的条件：相关处理适用于窄带雷达;全去斜处理适用于宽带雷达,以及射频噪声干扰和混沌相干干扰对这2种脉冲压缩技术的干扰效果,并分别进行了仿真实验。结果表明：在干信比相同的条件下,射频噪声干扰对窄带雷达影响显著,混沌相干干扰对这2种脉冲压缩技术都能造成强有力的干扰。

After simply introducing the principle of correlation processing and stretch processing, which are commonly used by radar pulse compression, the applicable conditions of each technique are analyzed in detail：correlation processing is usually used in narrow bandwidth radar, while stretch processing is normally used to process wide bandwidth LFM waveforms, when the radars are in the same waveband. Following this, two interfering methods, radio noise jamming and chaotic coherent jamming, are analyzed upon these two pulse compression techniques. The interfering effects are contrasted respectively by simulations. The result shows that radio noise can jam narrow bandwidth radar prominently; chaotic coherent noise can strongly jam both of these two pulse compression techniques, on condition that the jam signal rate is same.
