Abstract: In this paper, the basic Multiple Input and Multiple Output ambiguity function tool is used to analyze the performance of orthogonal waveforms for MIMO radar antenna system. The orthogonal waveforms like modified Discrete Frequency Coding Waveform Linear Frequency Modulation (DFCW_LFM), Polyphase and Discrete Frequency Coding Space Time Waveform (DFCSTW) waveforms are considered. The resolution performance is governed and controlled by the system on transmit using orthogonal waveform diversity. The resolution performance is illustrated using MIMO radar orthogonal waveforms.
