<p>A signal processor includes a unit for forming designated groups from radar reflection signals, a memory unit for storing the designated groups of radar reflection signals individually, a first calculator for calculating a standard background signal SB from each of the designated groups of radar reflection signals stored individually. The signal processor further includes a second calculator for calculating differential signals between the individual radar reflection signals and the standard background signal SB separately for each of the designated groups and a unit for identifying the signal reflected from a search object out of the differential signal.</p> |
