<p><P>PROBLEM TO BE SOLVED: To obtain a radar signal processing apparatus, eliminating blur and smear of an image by reducing a phase correction amount calculating error due to fluctuations of a detected reference point frequency. <P>SOLUTION: A point group on a trajectory, detected by an amplitude maximum detecting circuit 10, undergoes a coordinate conversion by a coordinate conversion circuit 14 to be projected onto a point on a parameter space, after undergoing a coordinate conversion. In a linear component extracting circuit 15, the projected point is extracted on the parameter space. The point extracted by the linear component extracting circuit 15 is reversely projected onto the original coordinate space through a reverse coordinate conversion by a reverse coordinate converting circuit 16, enabling determination of a linear component included in the trajectory prior to the coordinate conversion. <P>COPYRIGHT: (C)2003,JPO</p> |
