In this paper, we describe a method of frequency-hopping signal detection, which is one of the methods of spread spectrum, by time-frequency analysis. Since the frequency hopping signal is a non-stationary signal, the signal changes very quickly. Therefore, time-frequency resolution is very important for detecting such non-stationary signals. The method considered in this paper is a spectrogram and has the form of a squared expression of STFT. Although the resolution of the simulation results was not good, We could get ideas on methodology to improve the resolution by applying various window functions. In addition to Spectrogram, better time-frequency resolution can be expected if various Window functions are applied to methods such as Scalogram, WVD, PWVD, SPWVD, S-Transform.
