摘　　要：雷达的广泛应用使雷达间的干扰问题变得越来越严重。同频雷达之间存在着严重干扰。同频雷达干扰可能产生的效应有:雷达接收机前端硬件损伤,接收机高频前置放大器饱和,虚警增加,雷达探测距离下降等。本文分析了同频雷达间干扰产生的原因,给出了抗雷达间干扰的技术途径。最后,提出了一种实用的抗同频干扰的方法——相参积累法。介绍了技术实现方案,建立了相参积累法的计算机仿真模型。计算机仿真结果表明,相参积累法能够有效抑制同频干扰。The wide uses of radar cause the problem of the interference between radars getting serious. There are serious interferences between radars with same frequency. The interference between radars with same frequency may bring many of effects, such as hardware damage of radar receiver front circuit, receiver preamplifier saturation, false alarm increasing,and the detection range decrease. The paper analyzes the reasons of the interference between radars with same frequency, and gives the anti-jamming approaches. Finally, an applied anti-jamming technology, coherent accumulation, is put out. The technique project is introduced, and the model of coherent accumulation is set up. The resolute of simulation shows that coherent-accumulation technique can restrain effectively the same frequency interference.
