Abstract
In previous studies, a multi-mode phased array system was described which simultaneously transmits a set of uncorrelated pseudo-random Golay codes and then, upon reception, isolates the signals and their associated modes using correlation receivers. In this study the performance of the same system is evaluated under the presence of moving targets and clutter through the use of a generalized ambiguity function and a system signal-to-noise ratio formula. Results indicate that, although the special Golay code properties of self-noise and cross-correlation cancellation are diminished as the velocity of a target increases, the degradation of system performance will be minimal for all but the fastest moving targets in medical imaging applications. For most practical imaging situations the Golay code simultaneous multi-mode transmission system will still provide an improvement in speed and/or signal-to-noise ratio over conventional sequential multimode systems.
