Abstract
An apparatus includes an ultrasonic sensor array and a sensor controller. The sensor array includes a plurality of ultrasonic sensor pixels, each sensor pixel including an ultrasonic receiver and a receiver bias electrode and being operable in one or both of a transmit mode of operation or a read mode of operation. The sensor controller is electrically coupled with the receiver bias electrodes. The sensor controller is configured to set, at each sensor pixel, a range gate window (RGW) by modulating a bias voltage applied to the receiver bias electrode and to set, for a first portion of the ultrasonic sensor pixels, a first RGW. The sensor controller is configured to set, for a second portion of the ultrasonic sensor pixels, a second RGW, and establish a first temporal delay between the first RGW and the second RGW.
