Abstract :
A two-million-channel 40-MHz-bandwidth, digital spectrum analyzer is described. Its synchronization and configuration control are discussed. The two-million-point matrix discrete Fourier transform at the core of the analyzer, which transforms the time-domain input signal into the frequency domain, is examined. The real-adjust stage and frequency-domain processing modules are also highlighted. The analyzer system will serve as a prototype processor for the sky survey portion of NASA´s search for extraterrestrial intelligence program and for other applications in the deep space network
