Abstract
The disclosure relates to an object size estimation device and method. According to the disclosure, an object size estimation device comprises a reception unit receiving a reception signal reflected by the object, through the reception antenna, an object length calculation unit calculating a reflection point based on a position frequency of measurements included in the reception signal, calculating a horizontal length of the object based on a distance between a first straight line passing through the calculated reflection point and a measurement and calculating a vertical length of the object based on a distance between a second straight line orthogonal to the first straight line and a measurement, and an object size estimation unit estimating a size of the object formed with the horizontal length and the vertical length.
