Quantum-based systems are an emerging topic of research due to their potential for increasing performance in a variety of classical systems. In radar and communication systems, quantum technologies have been explored in an effort to increase the correlation performance in the low signal-tonoise ratio (SNR) regime. While this increase has been shown both mathematically and in the laboratory using bipartite states, systems utilizing multi-partite squeezing and entanglement may lead to an even further performance increase. We investigate this by analyzing the correlation coefficient for a tripartite system electric field measurement to determine how it compares to the bipartite systems in the current literature for the same transmit powers. This is done by defining a tripartite wave function in terms of the mean photon number per mode then determining the covariance matrix from this wave function. This work is important in understanding how alternative states of light can be used for quantum radar applications.
