1. A system comprising: a radar device, including: a transmitter configured to transmit a radar signal; and a receiver configured to receive a reflected signal, the reflected signal being the radar signal reflected from one or more objects; and an object detecting device, including: a processor configured to: calculate an intensity of reflection, which is a representative value of received power of the reflected signal, for each of cells obtained by partitioning an azimuth angle with respect to the radar device and a distance from the radar device at predetermined intervals; generate profile information indicating the intensity of reflection; calculate a cell which has a local maximum value of the intensity of reflection as a capture point of the one or more objects based on the profile information of each cell; calculate at least one or more capture regions, each being an aggregation of cells including the capture point, based on the profile information of each cell and the capture point; select, if a plurality of capture regions are calculated, a reference capture region and a proximity capture region that is present within a predetermined distance from a capture point of the reference capture region from the plurality of capture regions; determine whether or not to group the proximity capture region and the reference capture region into one capture region based on information on the proximity capture region and information on the reference capture region; determine a type of the object based on a shape of a capture region obtained as a result of grouping; and output, to an avoidance device, object determination information related to the determined type of object.
