Abstract
An ultrasonic pulse echo apparatus detects an object that is moving with respect to stationary objects. An ultrasonic transducer transmits a series of ultrasound pulses in a direction that intersects a path of the moving object. An ultrasound receiver receives a series of lines of echoes from objects in the field of view of the ultrasonic signal. Each echo line corresponds to one of the ultrasonic pulses. A signal processor processes the echo lines from the moving object. The echo lines are time shifted by different amounts and combined at different time shifts to produce different composite lines. The composite line having an optimal signal-to-noise ratio is selected. Other signal processing enhancements are performed.
