发明名称 Multipath signal judging method, program, and multipath signal judging device
摘要 A multipath signal judging method includes: performing correlation calculation for I and Q components for a reception signal as a positioning signal modulated in a spread code and a replica code; judging code phase based on the correlation calculation; calculating an angle formed by position vectors of correlation values at advanced phase and delayed phase from the code phase in advanced and delayed directions by N chip (0<N<1) plotted on IQ coordinates; and judging whether the reception signal is multipath signal using the angle.
