A multiple-beam energy transmission system for the simultaneous transmission of at least two beams of energy directed in different directions from a single multi-element transducer assembly includes a signal source arranged to generate a train of successive signal pulses. Signal modifying circuitry associated with each element is provided for modifying the phase of each successive signal pulse by applying to each successive signal pulse a complex aperture weighting function, different phase shifts being applied to successive signal pulses, the phase shifts applied for one beam being unrelated to those applied for another. Control circuitry controls operation of the signal modifying circuitry such that the complex aperture weighting function applied to each successive signal pulse from the signal source by the signal modifying circuitry results in the radiation of the required beams of energy from the multi-element transducer assembly.
