Provided is a micro robot position detection device. The device includes a micro robot position detection unit that uses a micro robot control parameter to filter a reflected signal of an ultra wide-band impulse radar signal emitted to a micro robot to extract, as a micro robot signal, a natural oscillating frequency signal generated when the micro robot is driven through control of external electromagnetic field, and analyzes the micro robot signal based on a transmission and reception parameter of the ultra wide-band impulse radar signal to calculate position information for the micro robot. Also, the device may further include an image matching unit that receives position information for the micro robot and performs position correction on the received position information based on pre-stored reference image data and the image data.
