Abstract
A digital spectrum analysis apparatus and method for direction finding (DF) and location is provided. The digital spectrum analysis apparatus for single-channel direction finding includes: a digital processing unit configured to receive a signal, convert the received signal into a digital signal, reduce a sampling rate of the digital signal by using a digital down converter (DDC), and convert the digital signal into a baseband complex signal; a spectrum processing unit configured to map a bearing and a power level of the baseband complex signal into coordinate system, and allocate different colors to the power levels depending on the accumulation ratio of the power levels; and a display unit configured to display the power levels with colors in order to estimate the bearing of the signal.
