摘要: In a method of using an ultrasonic sensor comprising two-dimensional array transducers, plurality signals are transmitted according to beamforming pattern at position the array. The focuses location above array, wherein identifies transducers that activated during transmission signals, and least some phase delayed with respect other pattern. At one reflected signal is received receive pattern, receiving. transmitting receiving repeated positions
