摘要
The method involves processing the signals of two groups of transducer pairs formed from identical groups, each containing at least one transducer and arranged on both sides of two mutually inclined axes, using an electronic signal processor. The method involves forming first and second groups of transducer pairs from identical groups, each containing at least one transducer and arranged on both sides of two mutually inclined axes. First and second amplitude summation signals are computed from the amplitudes of the complex output signals of the first and second groups using an electronic signal processor. First and second difference amplitude signals are computed from the complex output signals of the two groups. Resultant output signals for two main beam formation planes are computed and combined by multiplication to form a three-dimensional focused directional beam.
