Method acoustics

WebNon-cooperative passive detection is a new type of underwater acoustic detection technology, which originated in the field of radar. It detects the target scattered echoes through active signals emitted by non-cooperative sources. Since this mode can perform high-gain detection of long-distance targets without transmitting a detection signal, it has … WebMixed Method in Acoustic Research Acoustics research must be measured by quantitative method based on the sound characteristics. Sound is non-physical subject and it fills all parts of space, and therefore, to obtain …
