Electro-Explosive Detonator (EED) is the main trigger mechanism in most of the explosive systems. Explosion of these systems start with the burning of the EED bridge wire by excess current, followed by the explosion of higher amount of explosives. Accidental or on purpose explosion of these explosives results in many losses. The electrical properties of the EEDs are modeled at the microwave frequencies, but there is no focus on the detection of EEDs by their RF signature. MUltiple SIgnal Classification (MUSIC) and Prony’s methods are adopted for this purpose, and measurements are conducted for justifying the methods. A Multiple Input Multiple Output (MIMO) measurement system is also setup and detection performance enhancement is achieved by statistical MIMO application.
