    • A system and method for detecting the presence of an RF device and determining a location of the RF device. The system includes a first antenna capable of transmitting a first radar signal and receiving RF signals, a second antenna capable of transmitting a second radar signal and receiving RF signals, where the second radar signal is offset in frequency from the first radar signal, and one or more processors. The one or more processors analyzes harmonic and intermodulation (IM) signals generated in response to the first radar signal and the second radar signal interacting with nonlinear characteristics in components of a RF device. The analyzing provides detection of the presence of the RF device and the determination of a location of the RF device regardless of whether the RF device is active or passive.
    • 一种用于检测RF设备的存在并确定RF设备的位置的系统和方法。 该系统包括能够发送第一雷达信号和接收RF信号的第一天线,能够发送第二雷达信号并接收RF信号的第二天线,其中第二雷达信号在频率上偏离第一雷达信号,一个 或更多的处理器。 一个或多个处理器分析响应于第一雷达信号产生的谐波和互调(IM)信号,以及与RF设备的部件中的非线性特性相互作用的第二雷达信号。 该分析提供对RF设备的存在的检测和RF设备的位置的确定,而不管RF设备是主动还是被动。
