无线传输正在成为无源雷达检测日益广泛使用的传输源。在本文中，我们对一系列实验中获得的一系列典型 IEEE 802.11 信号的模糊函数 (AF) 进行了详细分析。理论分析已用于识别基本信号类型在距离和多普勒域中的分辨率和旁瓣水平方面的平均特性。一系列典型 802.11 传输的理论模型已经过验证，并且已经针对一系列传输类型研究了范围和多普勒分辨率。已经发现，使用具有合适积分时间的多普勒可以检测典型的人员目标。在本研究中已经确定了与这些传输的使用相关的许多问题。
Wireless transmission is becoming an increasingly widely available source of transmissions for passive radar detection. In this paper, we present a detailed analysis of the ambiguity function (AF) of a range of typical IEEE 802.11 signals obtained during a series of experimental trials. Theoretical analysis has been used to identify the average properties of basic signal types in terms of resolution and sidelobe levels in both the range and Doppler domains. The theoretical model of a range of typical 802.11 transmissions has been verified and range and Doppler resolutions have been investigated for a range of transmission types. It has been found that using Doppler with a suitable integration time can enable detection of typical personnel targets. A number of issues relating to the use of these transmissions have been identified during this study.
