摘要：
这项工作的特点是在一个平面网络的脉冲雷达设备的相互干扰的影响。使用随机几何工具和最强的逼近，我们推导出简单的封闭形式的表达式，精确的雷达检测范围和虚警率在干扰限制区域的关键系统参数所发挥的作用。雷达性能，网络密度和天线方向性之间的系统的基本权衡捕获不同的路径损耗指数在无衰落和瑞利衰落的情况下。讨论突出了调整雷达参数的实际设计提示。通过网络仿真验证了模型的准确性，并描述了随机噪声在稀疏、非干扰受限网络中对检测的作用。
英文摘要：
This work characterises the effect of mutual interference in a planar network of pulsed-radar devices. Using stochastic geometry tools and a strongest interferer approximation, we derive simple closed-form expressions that pinpoint the role played by key system parameters on radar detection range and false alarm rate in the interference-limited region. The fundamental tradeoffs of the system between radar performance, network density and antenna directivity are captured for different path-loss exponents in the no-fading and Rayleigh-fading cases. The discussion highlights practical design hints for tuning the radar parameters. The accuracy of the model is verified through network simulations, and the role of random noise on detection in sparse, non interference-limited networks is characterised.
