<p>PURPOSE:To suppress clutter being an unnecessary signal without receiving the effect of a target signal having a large power value even when said signal is received. CONSTITUTION:A plurality of reflection coefficients calculated by reflection coefficient calculating means 1a, 1b are transmitted to median filters 9a, 9b. The intermediate values of the reflection coefficients are selected by the median filters to be used as reflection coefficients used in processing and, therefore, even when a reflection coefficient containing the data of a target signal is present in the reflection coefficients transmitted to the median filters, since said data is rejected by the median filters and only clutter data remains, it is prevented that the suppressing capacity of clutter is deteriorated by the effect of the target signal.</p> |
