标题： Ranging success probability of PPP distributed automotive radar in presence of generalized fading

摘要： 在汽车雷达应用中，所有车辆都使用多个雷达以提高成像质量。然而，这会导致来自邻近车辆的雷达间干扰，从而降低成像质量。 衡量成像质量的一个指标是测距成功概率。 测距成功概率是指在特定工作条件下，多雷达系统在给定距离上成功检测到物体的概率。 在现有文献中，假设期望信号分量没有衰落的情况下，已经推导出了测距成功概率的闭合表达式。 同样在文献中，尽管假设干扰信号的衰落分布是任意的，但仅针对干扰信号无衰落的情况推导出了闭合表达式。 由于无线信道中衰落始终存在，我们假设期望信道经历流行的瑞利衰落，推导了测距成功概率。 并且我们假设干扰信道服从广义的$\kappa$-$\mu$阴影衰落，该模型概括了许多流行的衰落模型，如瑞利、莱斯、Nakagami-$m$， $\kappa$-$\mu$等。 假定干扰源位于从泊松点过程分布中抽取的点上。 我们还研究了阴影成分与聚类数量之间的关系如何影响视距（LOS）成分对测距成功概率的影响。 显示英文摘要

摘要： In automotive radar applications, multiple radars are used in all vehicles for improving the imaging quality. However this causes radar-to-radar interference from neighbouring vehicles, thus reducing the imaging quality. One metric to measure the imaging quality is ranging success probability. The ranging success probability is the probability that a multiple radar system successfully detects an object at a given range, under certain operating conditions. In state-of-the-art literature, closed form expressions for ranging success probability have been derived assuming no fading in desired signal component. Similarly in literature, though distribution of fading in interferers is assumed to be arbitrary, closed form expression is derived only for no-fading assumption in interferers. As fading is always present in a wireless channel, we have derived ranging success probability assuming desired channel experiences the popular Rayleigh fading. And we have assumed generalized $\kappa$-$\mu$ shadowed fading for interfering channels that generalizes many popular fading models such as Rayleigh, Rician, Nakagami-$m$, $\kappa$-$\mu$ etc. The interferers are assumed to be located on points drawn from a Poisson point process distribution. We have also studied how the relationship between shadowing component and number of clusters can affect the impact of LOS component on ranging success probability.
