A probability model of stationary object using radar time-frequency spectrum

Abstract

In this paper, we suggest a probability model of stationary object for classifying the stationary and moving objects using radar time-frequency spectrum. In radar spectrum, the stationary object has a slope that matches the velocity of ego vehicle. Applying the Hough transform, the slope is estimated and converts to velocity. The difference between the velocity of ego vehicle and estimated velocity is used to compare characteristic of the stationary and moving objects. We experimentally compare characteristic of the objects and suggest a probability model of stationary object using exponential distribution.
