Abstract

Within aerosol-rich environments, efficient simulation of frequency-modulated continuous wave (FMCW) laser detector echo characteristics is crucial. Conventional methods often need more efficiency. To address this, we propose a photon matrix-based approach for simulating intricate photon scattering processes, enhancing simulation accuracy. This study focuses on short-range FMCW laser detection under aerosol interference, assessing performance via signal-to-noise ratio (SNR). We analyze the impact of amplitude modulation coefficient and photon count on SNR. Surprisingly, the photon count minimally affects SNR, while the amplitude modulation coefficient significantly influences it. These findings shed light on optimizing FMCW laser detection in aerosol-laden environments. Attention to the amplitude modulation coefficient can notably enhance SNR and overall detection efficiency.

利用光子矩阵增强气溶胶散射的蒙特卡罗模拟

在富含气溶胶的环境中，高效模拟频率调制连续波（FMCW）激光探测器的回波特性至关重要。传统方法往往需要更高的效率。为此，我们提出了一种基于光子矩阵的方法来模拟复杂的光子散射过程，从而提高模拟精度。本研究侧重于气溶胶干扰下的短程 FMCW 激光探测，通过信噪比 (SNR) 评估性能。我们分析了振幅调制系数和光子数对信噪比的影响。令人惊讶的是，光子数对信噪比的影响很小，而振幅调制系数对信噪比的影响却很大。这些发现为优化气溶胶环境中的 FMCW 激光探测提供了启示。关注振幅调制系数可以显著提高信噪比和整体探测效率。
