<P>PROBLEM TO BE SOLVED: To provide a technique for preventing a number of components of a radar system from increasing and suppressing heat generation. <P>SOLUTION: A detection point related to an object is derived in one signal processing period based on a first transmission wave and a second transmission wave having a prescribed period and a first reflection wave in which the first transmission wave is reflected on the object and a second reflection wave in which the second transmission wave is reflected on the object. When prescribed conditions are satisfied, the detection point is derived in one signal processing period based on the first transmission wave changed into a specified period longer than the prescribed period and the first reflection wave, and the detection point is derived in the next signal processing period based on the second transmission wave changed into the specified period and the second reflection wave. As a result, the heat generation of the radar system can be suppressed almost without delaying deriving processing for the angle of the object. <P>COPYRIGHT: (C)2013,JPO&INPIT |
