A phased array radio frequency pulse generator includes a plurality of radio frequency pulse generator units (4, 4a, 4b, 4c Fig 3 not shown) each having a non-linear dispersive electrical circuit 1 incorporating at least one non-linear element 5 including a material sensitive to low power signals 7 and a means 6 for producing a variable power control signal 7 and applying it to be at least one non-linear element 5 to modify the extent of the non-linearity of the element and thereby vary the timing of the radio frequency electrical output signal generated. Means 13 is provided for adjusting the value of the control signals 7 provided in each unit (4, 4a, 4b, 4c), to vary the relative phases of the output signals from the units (4, 4a, 4b, 4c) in a phased array on a pulse to pulse basis. |
