End-fire array
WebOct 23, 2024 · A differential end-fire array always has a null at 180 degrees, and this null is independent of wavelength. Now consider sounds arriving from the on-axis (opposite) direction, traveling from microphone 2 toward microphone 1. Because of the time delay τ, the signal from microphone 2 will be delayed by 2τ relative to the signal from microphone 1. Web1. The array is said to be broadside array if the direction of maximum radiation is perpendicular to the array axis. The array is said to an end-fire array if maximum radiation is along the array axis. 2. In broad side, phase difference α = 0. In end fire, phase difference between adjacent element is α= -βd.
