This paper proposes a new configuration of acoustic sensors—the collocation of three cardioid sensors in perpendicular orientation, in order to increase the mainlobe-to-sidelobe height ratio (possibly to <inline-formula> <tex-math notation="LaTeX">$\infty$</tex-math></inline-formula>). This paper will analyze such a proposed triad's “spatial matched filter” beam-pattern that is independent of the frequency/spectrum of the incident signals. Specifically, this paper will analytically derive the…
