Abstract:
The dif ference f requency‘ s spect rum of saw tooth waveform linear FM f ix distance system is analyzed w hen echo delay time is much less than modulate period. It is proved that amplitude of primary f requency is much larger than that of other frequencies at a single delay w ith designed parameters so that Goertzel algorithm can be utilized to analyze the spectrum. A fast signal processing method for saw tooth waveform linear FM f ix distance system is provided w ith Goert zel algorithm, this method can reduce the complex ity of calculat ion.
