A phased array sector scanning ultrasonic imaging system includes a transducer array with 2N separate transducer elements and a transmitter and receiver with N separate channels. The complete 2N element aperture is realized at each beam angle with two firings of the transmitter and the receipt of echo signals from two different sets of N transducer elements. The echo signals from the two firings are coherently summed to form a single receive beam. Two different patterns are provided for selecting which transducer elements to energize and receive from during each of the two firings.
