A system for drawing a map of hidden geographical features

PURPOSE: A detailed image painting system is provided to paint an image for a shielded geographical feature based on geometry information by acquiring the geometry information by using an UWB(Ultra Wide Band) signal. CONSTITUTION: A driving unit drives an UWB(Ultra Wide Band) exploration device(100) on a curved ground. A left and a right arm unit(130a,130b) are rotated in the driving of the UWB exploration device by the rotation force of a driving motor of a main body unit(120). An UWB radiator(150) radiates an UWB signal from a front surface of a cradle member(140). An UWB receiver(160) receives the UWB signal reflected from the ground from a lower front end of the cradle member. A communication control apparatus(170) controls the reception of a control signal and the transmission of geometry information of the shielded geographical feature by using a control signal.
