Directivity Index
The directivity index measures the ability of a transducer to reject noise from extraneous sources. In the
ocean, noise may be coming from all directions, but a narrow beam transducer will only “hear” noise
within the beam width pattern. A sonar systems signal to noise ratio (SNR) will be affected by the ability
of a transducer to reject unwanted noise, and thus is related to the directivity index. The higher the
directivity index of a transducer, the better the ability to reject unwanted noise.
