Figure 1From: Double-Capon and double-MUSICAL for arrival separation and observable estimation in an acoustic waveguideSchematic representation of two raypaths propagating in the waveguide. The two raypaths have close DOAs (near = θ 0 r ) and TOAs (proportional to the raypath length for a homogeneous medium), but have DODs θ 1 e and θ 2 e that are significantly different.Back to article page
