Abstract : The primary objective of radar is to identify a target in various scenarios. Radar signal generation with various coding and modulation schemes are introduced from earlier times to recent times for this purpose. There are not much efficient waveforms available for a radar system to identify a target, hence a new waveform modulation is always needed. In the work discussed here, a stepped frequency waveform (SFW) is modulated with two waveforms such as cyclic prefix - orthogonal frequency division multiplexing (CP-OFDM) and discrete fourier transform-spread-orthogonal frequency division multiplexing (DFT-S-OFDM) in order to improve the complexity of the waveform and to obtain pulse compression. This CP-OFDM and DFT-S-OFDM are the new waveform candidates that are expected to use in 5G communication systems. The modulated waveforms are analyzed with a clutter model in order to test whether this waveform design can be used in a radar system for the purpose of target identification in the midst of clutter. The modulated waveforms are analyzed using ambiguity functions
