Abstract :
LPI (low probability of intercept) radars occupy wide frequency bands and have very low peak power so they are difficult to be detected by hostile intercept receivers. Hostile radiometric receivers are not able to intercept and measure the parameters of LPI signals which lie in wide frequency bands. In this study, four different methods for the analysis of LPI signals; zero-crossing method, short time Fourier transform (STFT), Wigner-Ville distribution (WVD) and cyclostationary signal analysis method are investigated and their performances on LPI signals are presented by utilizing computer simulations
