ATC Transponder-The Design and Application of a Magnetostriction Delay Line for Coding Purposes

In order to meet operational requirements high pulse position accuracy is required for the reply-code pulses transmitted by the ATC Transponder. The use of a magnetostriction delay line as the primary delay element for positioning the constituent pulses of the reply code groups is discussed. The design of a magnetostriction delay line for this purpose is discussed and a method for remote selection of the reply codes is presented.
