Zero interleaved mutually orthogonal sequences for high frame rate synthetic transmit aperture

Ideally, when trying to accelerate synthetic transmit aperture (STA) while avoiding long deadzones in front of the probe, short sequences with zero cross-correlation function (CCF) and a delta impulse autocorrelation function (ACF) are to be transmitted simultaneously by all elements in a single transmit event. However, sequences with these correlation properties does not exist. In this study we introduce new sequences based on mutually orthogonal complementary pairs (MOCPs) interleaved with intervals of zeros to achieve high frame rate STA with high SNR while maintaining a reasonable blind zone area.
