A system and method for ultrasonic sensing, wherein an ultrasonic receiver array includes multiple ultrasonic sensor pixels, and each sensor pixel includes an ultrasonic receiver configured to read an ultrasonic signal. An ultrasonic transmitter array, composed of multiple elements, transmits ultrasonic signals which may be reflected from an object and received at the ultrasonic receivers, wherein a sensor controller applies excitation signals to the transmitter array with a temporal delay between excitation signals.
