Abstract

A signal selecting device is provided. The signal selecting device includes a transceiver for repeatedly transceiving electromagnetic waves, a target candidate detecting module for detecting a plurality of objects based on echo signals received by the transceiver, a phase change amount calculating module for calculating a phase change amount between two echo signals from two positions of which distances from the transceiver are substantially the same but azimuths from the transceiver are different, and an object selecting module for selecting a predetermined object among the plurality of objects detected by the target candidate detecting module in a first scan based on a phase change amount of the object, the predetermined object being the same object as an object selected by the object selecting module in a second scan that is performed before the first scan.

First claim

What is claimed is:

1. A signal selecting device, comprising:
a transceiver for repeatedly transceiving electromagnetic waves;
a target candidate detecting module for detecting a plurality of objects based on echo signals received by the transceiver;
a phase change amount calculating module for calculating a phase change amount between two echo signals from two positions of which distances from the transceiver are substantially the same but azimuths from the transceiver are di…
