Abstract :
Multiple Input Multiple Output (MIMO) radars transmit partially coherent or noncoherent waveforms for improving spatial resolution or spatial diversity. While waveform design for SIMO radars concentrate on improving the delay and Doppler resolution characteristics, waveform design for MIMO radars involve optimization of delay, Doppler and spatial resolution characteristics. MIMO radar ambiguity function of frequency hopping waveforms is recently derived. In this paper, MIMO radar ambiguity function of phased coded pulse waveforms is derived. Polyphase pulse waveforms based on Kumar sequences are analyzed using this derived MIMO ambiguity function through simulations.
