Abstract: An object detection method performed by a movable device is provided. The object detection method includes emitting radio frequency signals, receiving radio frequency signals reflected by an object, obtaining N sample sequences by digitizing N radio frequency signals, N being a natural number greater than or equal to 2, from among the received radio frequency signals, obtaining a matrix including each of the N sample sequences as a column, in an order in which the radio frequency signals are received, obtaining a resulting signal by summing samples for each row of the matrix and obtaining an energy value from the resulting signal, and detecting the object based on the obtained energy value being greater than or equal to a certain threshold value.

Abstract: An electronic device and a method of determining a path of the electronic device is provided. The method includes emitting a signal in a direction of a surface and receiving a signal reflected from the surface or a subsurface, obtaining an image of a structure of the surface or a structure of the subsurface, based on the received signal; when it is possible to determine a location of the electronic device based on the obtained image and an image pre-stored in the electronic device, determining the location of the electronic device, and when it is impossible to determine the location of the electronic device based on the obtained image and the image pre-stored in the electronic device, obtaining surrounding environment information of the electronic device by using a second sensor and determining the location of the electronic device.
