SIGNAL DETECTION APPARATUS AND METHOD, AND PARAMETER SETTING METHOD OF THE SIGNAL DETECTION APPARATUS

摘要

PURPOSE: An apparatus and a method for acquiring signals and a method for setting the parameter of the apparatus are provided to reduce the processing amount of a correlation operation by controlling the frequency resolution of a signal acquired from a satellite navigation receiver. CONSTITUTION: A sampling module(110) samples a signal, received from a satellite, and a pre-set PRN code according to pre-set signal acquiring frequency. A correlation operator(120) implements a correlation operation with respect to the signal and the PRN code. A Fourier transformer(140) implements a Fourier transformation operation with respect to the frequency resolution of the correlation operated result according to a pre-set Fourier transformation point. A peak detector(170) detects the peak of an energy value based on the Fourier transformed result.
