Abstract

The current methods of detecting targets operate based on interference, clutter, noise, parameters and/or on signal Doppler specifications. There is no optimum detector for a general environment in unknown Doppler shifts. In this paper based on the combination of tolerance interval technique and time-frequency signal analysis, a new method is presented to introduce a new detector. The method is non-parametric, signal is analyzed in time-frequency domain by its spectrogram and the time interval of signal presence is determined. Finally, the adaptive thresholding is utilized and signal detection is fulfilled.
