论文摘要
在汽车雷达应用中，在所有车辆中使用多个雷达来改善成像质量。但是，这会导致相邻车辆的雷达到雷达干扰，从而降低了成像质量。一个测量成像质量的指标是成功概率。范围的成功概率是多个雷达系统在某些操作条件下成功检测到给定范围的对象的概率。在最先进的文献中，假设所需的信号成分中没有褪色，则得出了用于范围成功概率的封闭形式表达式。同样，在文献中，尽管认为干扰物中褪色的分布被认为是任意的，但仅用于干扰物中的无衰落假设而得出封闭形式的表达。由于无线通道中始终存在褪色，因此，假设所需的频道体验流行的瑞利褪色，我们已经得出了范围的成功概率。而且，我们假设$κ$ - $ $ $ $ $ shadowed vading用于干扰频道，这些频道概括了许多流行的褪色模型，例如雷利，里奇亚人，中国nakagami- $ m $，$κ$ - $ - $ - $ - $ $等。假定干扰器位于Poisson Point Posspection的点上。我们还研究了阴影组件与簇数之间的关系如何影响LOS组件对成功概率的影响。
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 $κ$-$μ$ shadowed fading for interfering channels that generalizes many popular fading models such as Rayleigh, Rician, Nakagami-$m$, $κ$-$μ$ 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.
