Digital Pulse Electronic Harmonic Radar Electronic Device Detector

The system is based on the nonlinear properties of semiconductor components and metal contact points in electronic devices, which reflect electromagnetic waveforms. It aims to develop a portable and intelligent frequency-modulated continuous wave nonlinear node detector capable of detecting electronic devices and metal devices. The research includes the design of radar waveform generators and transmitters, harmonic receivers, antenna arrays, signal processing circuits, and display control components. The ultimate goal is to create an operational and practical nonlinear node detector. Through this research, it is possible to enhance China's counter-surveillance and counter-monitoring capabilities, as well as improve the military's ability to detect underground unexploded devices.

The electronic device detector can be widely applied in venues and facilities related to government, public security, prisons, military, education, electronic factories, and other relevant departments. It serves as a tool for ensuring personal and facility security, maintaining confidentiality, and conducting counter-terrorism security checks.

The electronic device detector is a handheld application of harmonic radar technology. It offers high sensitivity, low false alarm rate, strong anti-interference capability, stable operation, compact size, lightweight, optimized human-machine interaction interface, and easy operation. It can detect various electronic products and metal objects in both powered on and powered off states. This includes items such as mobile phones, laptops, tablets, USB devices, storage cards, memory sticks, SIM cards, RFID devices, various types of cameras, wiretapping devices, wireless bugs, various recording devices, electronic modules, components, and other electronic devices.
