<p>PURPOSE:To well perform the detection of an object by enabling the suppression of an unnecessary signal adapted to each region, by respectively changing over filter factor to a fixed clutter region, a moving clutter region and clear region. CONSTITUTION:The titled apparatus is equipped with an input terminal 300 of a complex signal, a generator 340 for imparting weighing coefficient corresponding to a region to a sweep memory 311 and a weighting processing device 321, a sweep memory 312 and a weighting processing device 322..., a terminal 331..., a control signal generator 350 for generating a weighting factor changing-over signal, a region discriminator 360 for discriminating a region from an input signal and an adder 380 for adding the output signals of wighting multipliers 321-32N. In this case, corresponding to a generated region discriminating signal (to a fixed clutter region, a moving clutter region and a clear region), filter factor is changed over so as to obtain optimum filter characteristics to each region.</p> |
