Abstract
The search for an increase in medical imaging frame rate has been on-goingfor decades. A number of coding techniques may be applied based on simultaneoustransmission from multiple sub-apertures. Linear frequency modulated (LFM)signals or chirps is a coding technique with the ability to enhance the SNR butthe coding diversity is limited, for example up chirp and down chirp. In thispaper the cross-correlation properties are explored for the LFM and a closelyrelated variant employing a sinusoidal frequency modulation (SFM). As well asoffering a novel type of excitation, that behaves similarly to a standard chirp,the SFM also yields similar cross-correlation to chirps of opposite rate.
