<p><P>PROBLEM TO BE SOLVED: To provide a radar signal processor capable of restraining a clutter and a disturbance, and capable of holding a main probe to obtain high restraint performance. <P>SOLUTION: This radar signal processor is provided with a beam composing circuit 2 for beam-composing signals output from a main antenna 11, a Fourier transformation circuit 3 for Fourier-transforming an output from the beam composing circuit 2 to generate a main channel signal, a restraint auxiliary beam forming circuit 6 for subtracting a signal with an amplitude and a phase of a signal output from the Fourier transformation circuit matched to an amplitude and a phase of an auxiliary channel, from an auxiliary channel signal output from an auxiliary antenna 12, an adaptive processing circuit 4 for conducting adaptive processing by a tapped delay line, using a signal output from the restraint auxiliary beam forming circuit, and a canceling circuit 5 for restraining an unnecessary wave included in the main channel signal by subtracting an adaptive-processed signal from the main channel signal. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
