论文摘要
我们提出了一个称为Bistatic雷达检测覆盖范围概率的度量，以评估离散混乱条件下的Bistatic雷达的检测性能。这种情况通常是在室内和室外环境中遇到的，在室内和室外环境中，被动雷达接收器与机会性照明器部署。来自雷达环境的反向散射和多径会导致幽灵目标和点杂波响应，从而导致检测性能恶化。在我们的工作中，我们将杂物点建模为泊松点过程，以说明其数量和空间分布的多样性。使用随机几何配方，我们提供了一个分析框架，以估计信号与杂物和噪声比的概率高于目标雷达平面中任何特定位置的噪声比，高于预定义的阈值。使用度量标准，我们得出了有关噪声和混乱有限条件下雷达性能的关键雷达系统观点；可以将Biscistatic雷达框架近似于单稳定框架的范围；以及最佳的雷达传输功率和带宽。我们的理论结果通过蒙特卡洛模拟在实验上验证。
We propose a metric called the bistatic radar detection coverage probability to evaluate the detection performance of a bistatic radar under discrete clutter conditions. Such conditions are commonly encountered in indoor and outdoor environments where passive radars receivers are deployed with opportunistic illuminators. Backscatter and multipath from the radar environment give rise to ghost targets and point clutter responses in the radar signatures resulting in deterioration in the detection performance. In our work, we model the clutter points as a Poisson point process to account for the diversity in their number and spatial distribution. Using stochastic geometry formulations we provide an analytical framework to estimate the probability that the signal to clutter and noise ratio from a target at any particular position in the bistatic radar plane is above a predefined threshold. Using the metric, we derive key radar system perspectives regarding the radar performance under noise and clutter limited conditions; the range at which the bistatic radar framework can be approximated to a monostatic framework; and the optimal radar transmitted power and bandwidth. Our theoretical results are experimentally validated with Monte Carlo simulations.
