Coherent Multiple Input Multiple Output (MIMO) Radar utilizes orthogonal waveforms to allow for formation of both transmit and receive beams on receive. Many waveform sets have been proposed to accomplish this task: Orthogonal Frequency Division Multiplexing (OFDM), Linear Frequency Modulation on the Pulse (LFMOP), Noise waveforms, Golay Codes, Deng Codes etc. In "A novel polyphase code for sidelobe suppression,” Searle et al. proposed a special set of Modified Golay Codes that take advantage of a polyphase modulator along with frequency diversity to achieve orthogonality; however, this type of code increases the required number of sensor outputs along with the total bandwidth of the system to achieve its results. It is much more convenient to operate a MIMO system over a single bandwidth of interest while achieving sufficient orthogonality for Virtual Beamforming (VBF). This paper presents the experimental results for the simulation, in-the-loop testing, and open-air experimentation of the Modified Golay Code, LFMOP, and the windowed LFMOP. By testing the orthogonality of the modulation schemes while operating over the same bandwidth in a real environment, the research provides valuable feedback to guide future MIMO experimentation.
