<p><P>PROBLEM TO BE SOLVED: To prevent a clutter from being left unerasedly, without attenuating a target signal. <P>SOLUTION: This suppressor includes a clutter suppressing part 4 for calculating a filter coefficient forming a zero point in the center frequency of a clutter, and for suppressing the clutter contained in a reception signal of a pulse radar, using the filter coefficient, and clutter suppressing parts 7-1 to 7-N for calculating a filter coefficient forming a zero point in the center frequency added with an off-set frequency, and for suppressing the clutter contained in an output signal from the clutter suppressing part 4, using the filter coefficient, electric powers of output signals from the clutter suppressing parts 4, 7-1 to 7-N are compared with an electric power threshold value, and the output signals from the clutter suppressing parts 4, 7-1 to 7-N are selected in response to a comparison result to be output. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
