- Abstract
A method which bases on FPGA to realize the frequency-hopping (FH) signal analysis system is proposed. It designs a Radix-4 DIT FFT processing unit circuit firstly, then makes a Short-Time Fourier Transform(STFT) to FH signal and gets spectrum amplitude values. According to the features of the spectrum amplitude structure, we can obtain a non-linear mapping method which makes spectrum amplitude display more accurate, make a non-linear mapping transform of spectrum amplitude values, and get signal spectrum diagram of pseudo color index results.At last output the signal spectrum diagram of pseudo color displayed on VGA. Analysis FH signals and compare with Matlab simulation results, we can see that this design method is correct.
