Abstract
The present invention is a system and method for detecting devices with receivers, such as explosive devices with receivers used to remotely detonate the explosive devices. The system for detecting devices may include a transmitter which transmits a signal causing saturation of a device whereby harmonic content is emitted by the device. Receipt of an emitted harmonic signal which is coherent to the transmitted signal may indicate the presence of a device. A distance between the system and the detected device may be determined by modulating a frequency of the transmitted signal and measuring the time period between transmission of the signal and receipt of a harmonic signal. Additionally, direction information may be determined which may allow identification of a location of the device based upon the distance information and direction information.
