N2 - In increasing radar performance, radar waveform and waveform attributes are key elements. Among different waveforms, Linear Frequency Modulation (LFM) or simply chirp waveform attains best performance in terms of Doppler tolerance and time resolution. In analysing LFM waveform a Fractional Fourier Transform provides superior performance in time-frequency selective environment. Although Chirped Orthogonal Frequency Division Multiplexing OFDM is used to provide high data rate transmission it suffers from Peak to average power ratio (PAPR). Constant Envelope chirped OFDM is used to provide 0dB PAPR while providing high data rate transmission, this research studies Constant Envelope chirped OFDM as a radar waveform. Different simulations was conducted to check the performance of CE chirped OFDM in comparison to conventional OFDM and different waveform attributes was studied to check Doppler shift and time delay of the radar signal.
