Claim 14:
15. A method of signal transmission, comprising:
generating spatially and temporally encoded acoustic waveforms for interrogation of a target volume in a biological subject by:
transmitting, by a first transducer element on an array of transducer elements, after a time delay associated with the first transducer element, acoustic waveforms towards the target volume in the biological subject;
receiving, by a second transducer element on the array of transducer elements, after a round-trip time between the first transducer element and the second transducer element, returned acoustic waveforms that return from at least part of the target volume;

decoding the returned acoustic waveforms to isolate transmission of the acoustic waveforms transmitted by the first transducer element on reception by the second transducer element that correspond to a set of image points scattered from the target volume in the biological subject; and
processing the decoded returned encoded acoustic waveforms to beamform isolated echo samples for each image point of the set of image points of the target volume,
wherein the time delay is selected from a set of random time delays,
wherein the set of random time delays corresponds to a uniform distribution of random values within a range spanning from zero to a maximum tolerated standoff distance of the first and second transducer elements.
