Receiving and processing device, receiving and processing method, and receiving and processing program

A receiving and processing method processing data pieces of a plurality of receiving antennas acquired based on signals received by the receiving antennas constituting a receiving antenna array in which the plurality of receiving antennas are arranged at two or more irregular intervals, the method comprising the steps of:

• copying the data pieces of two or more continuous receiving antennas, in which one or more intervals from one end are different from a regular interval at the other positions, of the plurality of receiving antennas and arranging the copied data pieces so as to be added to the data pieces of the original two or more receiving antennas in such a manner that a position of the receiving antenna at the one end of the copied two or more receiving antennas is located at a position of the receiving antenna at the opposite end of the original two or more receiving antennas;
• inverting phases of the additionally-arranged copied data pieces of the two or more receiving antennas;
• rearranging the phase-inverted copied data pieces of the two or more receiving antennas so as to invert the arrangement of the data pieces;
• rotating the phases of the rearranged copied data pieces of the two or more receiving antennas so that the phases of two data pieces at the position of the receiving antenna at the opposite end of the original two or more receiving antennas match each other;
• and
• connecting the phase-rotated copied data pieces of the two or more receiving antennas to the data pieces of the original two or more receiving antennas by employing the data piece of the corresponding receiving antenna at the position of the receiving antenna at the opposite end of the original two or more receiving antennas.

A receiving and processing program processing data pieces of a plurality of receiving antennas acquired based on signals received by the receiving antennas constituting a receiving antenna array in which the plurality of receiving antennas are arranged at two or more irregular intervals, the program causing a computer to perform the sequences of:

• copying the data pieces of two or more continuous receiving antennas, in which one or more intervals from one end are different from a regular interval at the other positions, of the plurality of receiving antennas and arranging the copied data pieces so as to be added to the data pieces of the original two or more receiving antennas in such a manner that a position of the receiving antenna at the one end of the copied two or more receiving antennas with a position of the receiving antenna at the opposite end of the original two or more receiving antennas;
• inverting phases of the additionally-arranged copied data pieces of the two or more receiving antennas;
• rearranging the phase-inverted copied data pieces of the two or more receiving antennas so as to invert the arrangement of the data pieces;
• rotating the phases of the rearranged copied data pieces of the two or more receiving antennas so that the phases of two data pieces at the position of the receiving antenna at the opposite end of the original two or more receiving antennas match each other;
• and
• connecting the phase-rotated copied data pieces of the two or more receiving antennas to the data pieces of the original two or more receiving antennas by employing the data piece of the corresponding receiving antenna at the position of the receiving antenna at the opposite end of the original two or more receiving antennas.
